Chapter 1
The teaching voice
The voice is a fundamental tool of the teaching trade. It is used to communicate information, hold attention and keep order. Teachers talk for around 60 per cent of their working day, so itās not surprising that voice problems are common. For most, that means the occasional sore throat after a particularly hard day in the classroom but, for some, it means serious damage to the vocal cords that can threaten a career. Learning to use your voice more effectively will help keep it healthy ā and could make you a better teacher.
Statistics that speak loud and clear
Two separate surveys of UK voice clinics, both carried out since 2000, found that at least one in nine patients was a teacher; in Scotland, the figure was one in five. According to Voice Care Network UK, which conducted one of the studies, teachers are eight times more likely to suffer from voice problems than other professions. Other research published in the Journal of Voice in 1998 found that a fifth of all teachers experienced a problem with their voice during the teaching year. Another study reported in the same issue found that the same proportion of teachers, 20 per cent, had taken time off because of voice problems at some point in their career, compared with just 4 per cent of non-teachers.
Tool of the trade
Some teachers shout a lot, most teachers talk a lot, and all teachers face situations where they have to make themselves heard above background noise. Using your voice all day neednāt be a problem, as long as you are using it correctly. But whereas actors at drama school will work on their voice every day, a teacher at training college will be lucky to get a morningās lecture on the subject ā and if you qualified more than five years ago you may not have received any instruction at all. Not surprisingly, many teachers find that their voice is unable to cope with the demands. Research by Dr Stephanie Martin at Greenwich University in 2003, assessed the voices of 50 NQTs before they went out into the classroom. It found that 46 per cent had vocal qualities that gave cause for āsome concernā, while not one was starting their teaching career with a voice of āprofessional user qualityā. Not surprisingly, half of the sample group lost their voice at some point during their first year in the classroom.
Pitfalls of the profession
Another factor which can put your voice at risk is stress. Physical tension in the body has a negative impact on the quality of your voice and often leads to soreness. The classic confrontational posture ā with the jaw jutting forward ā is a trademark of many teachers, and is particularly bad for the voice. Other problems reported by speech therapists include teachers talking in too low a register to try to sound authoritative ā and even a primary teacher who talked through a fixed smile all day because she wanted to seem friendly.
All teachers need to look after their voices, but primary teachers face a particular challenge because the noise above which they need to be heard is usually at a higher pitch. Also at risk are physical education (PE) teachers who have to contend with echoing sports halls and windy playing fields.
Breathe easy
The first step to improving your use of your voice is to understand how it works. Speech is produced when breath passes over your vocal cords, causing them to vibrate. The sound is amplified by the resonating cavities in your chest, mouth and head. Then your lips, teeth and tongue shape the sound into recognizable words. Itās a natural, instinctive process. So what can go wrong?
One common failing is poor breathing. Snatching shallow breaths into your mouth or chest is a common side effect of a hectic lifestyle, but doing this involves the weak muscles around your neck rather than the strong muscles in the abdomen, and this puts pressure on your vocal cords. Correct breathing, using your diaphragm, takes the pressure off your neck and shoulders, and gives power to the voice. Itās important, too, that the air has a clear passage from the lungs to the larynx, which is where good posture is important. A slumped spine, hunched shoulders or a pushed-out neck could all cause tension and block the flow of air. A gentle massage of the neck and shoulders from time to time will help to relax muscles, but the way we breathe and stand are ingrained habits and it may take time and patience to change things.
Donāt put up . . .
Serious problems with your voice donāt come out of the blue. They are usually the result of prolonged misuse over weeks, months or years. And your body will provide you with plenty of warning signs along the way, if youāre prepared to take note. The classic distress signals are hoarseness and sore throats, especially first thing in the morning, or a feeling that the voice is āscratchyā and taking a long time to warm up. Perhaps you notice that your voice is getting stuck in a particular register, with less range than usual. Listen out, too, for any involuntary swoops or squeaks. If you sound like a teenager with a breaking voice, it may be because your voice is breaking in an altogether less happy sense.
. . . shut up!
Itās easy to assume that a sore throat is just part of the job and carry on regardless, but in doing so you could be risking more serious damage. If youāre struggling, take time off. An athlete who pulls a hamstring simply has to be patient, and itās the same for teachers with a sore voice. If you canāt bring yourself to stay at home, you may find that a class responds charitably if you explain the problem. Set them some work and practise a little amateur sign language. At the very least, try to build some quiet lessons into your timetable, and avoid unnecessary chatter in the staffroom. And when you do find yourself having to speak, ensure that you make an extra effort to talk properly, with good breathing. Whispering may seem like a good idea but itās actually likely to make things worse because youāre talking without proper breath support. If a few daysā rest doesnāt help, or if the problem recurs frequently, visit your GP, who will probably refer you to an ear, nose and throat specialist. If problems are dealt with in the early stages, changing a few habits should be enough to restore your voice to full health. However, prolonged abuse of the vocal cords can lead to nodules ā growths on the cords ā which may require surgery.
Healthy hints
As with looking after other parts of your body, there are general doās and donāts when it comes to voice care. For example, eating spicy foods late at night can cause a condition known as acid reflux, which damages the vocal cords. And eating too many dairy products can increase the amount of saliva you produce, bad for your voice, and not good either for those at the front of the class. Be careful, too, that you donāt make a nervous habit of clearing your throat. This makes the vocal cords clash together and causes wear and tear over time. And just as a sportsman takes time to warm up his muscles before serious action, try to get in the habit of warming up your vocal cords in the morning with some gentle humming or a sing-song in the shower.
Most teachers do much less talking in the holidays, so at the start of a new term, itās important to be extra careful, and try to ease yourself into the swing of things. Finally, remember that being in good general health will strengthen your voice. Being unfit and often out of breath will affect your voice, as will any viral throat infections you pick up.
Acoustics and aspidistras
Voice problems sometimes have their roots in the room where you teach. A cavernous, echoing classroom is likely to have you pushing your voice. There may be nothing you can do, but think about how you organize the room. Is it possible, for example, to set the desks up in such a way as to bring your audience closer? Central heating is another potential source of problems. The voice works best in a moist, well-ventilated room, but many modern classrooms are hot, dry and stuffy. Most people are more sensitive to temperature than moisture; we know if a room is too hot or too cold, but canāt always tell if itās too dry. But itās possible to buy gadgets that measure moisture and it may be worth persuading your school to invest in one. A good way of increasing moisture in a room is to have a few leafy plants dotted around. Opening a window will also help beat dehydration, as will having a glass of water to hand. Keeping the voice well watered is important; and most experts recommend drinking a couple of litres a day.Water at room temperature is best, and regular sipping is better than downing a large glass twice a day. Be aware that caffeine has a dehydrating effect, so too many cups of coffee wonāt do your voice any favours.
Speaking up for yourself
Voice care is an important health and safety issue. Every year a small number of teachers are forced out of the profession because of permanent damage to their voice. The teaching unions claim voice problems are a āforeseeable riskā and that employers have a duty to take āreasonable careā. So if, for example, you find yourself teaching in a classroom next to the school canteen and constantly having to make yourself heard above the noise, donāt be afraid to raise your concerns. If you canāt talk, you canāt work ā so itās in your schoolās interest to take the issue seriously.
In February 2002, a report published by the General Teaching Council for Scotland, Voice and the Teaching Profession, recommended that schools make more use of voice specialists to deliver in-service training days and advice to individuals. But the Voice Care Network warns that many UK schools are still unwilling to allocate sufficient time or money to voice training. Schools that do take the plunge are rarely disappointed. King Henry VIII school in Coventry, for example, booked a dayās workshop for all its staff, and followed up with another day for those who wanted it. āThe initial idea came from the staff,ā says director of studies Roger Howes, āand everyone got a lot out of it. But I can see that this is probably the sort of thing we need to have every year or so, not just as a one-off.ā
Finding your voice
Keeping your voice in good working order may seem more like a matter of personal health, rather than a classroom skill. But looking after your voice is the first step to making best use of it. Teachers want to be listened to, and having an interesting voice is almost as important as having interesting things to say. The way you use your voice will affect everything from how classes behave to how much they remember of what you tell them. Itās easy to fall into the trap of sounding like a caricature of a teacher, adopting the safe, dull voice of an authority figure. Or to think that talking loudly is the key to holding attention, even though most children switch off if they feel they are being ātalked atā rather than ātalked toā.
According to Lesley Hendy, a former lecturer in drama and education at Cambridge University and now a freelance voice tutor, the most common request by teachers at her workshops is āto learn how to shoutā. But the real skill of vocal delivery is modulating pause, pace, pitch and power, which means having a voice which is in good working order, and being in control of the basics, such as breathing and posture.
Most teachers find that a relaxed, well-produced voice has more ācolourā than one that is pushed or strained, and so holds the attention of the class more easily. And while it is quite possible to learn to project the voice, itās also true that clear articulation is sometimes more important than volume when it comes to being heard clearly and easily.
Discovering the full potential of your voice can be a lifetimeās journey, but even a few simple vocal exercises every day can soon bring about noticeable improvements. There are a growing number of voice books on the market, though most experts insist thereās no substitute for personal instruction ā at least to get you started.
In practice
As a teacher, my voice is my main weapon, and itās in constant use. I probably talk for around five hours a day, every day, but if I have a parentsā evening, it can be nearer to eight hours.
Iāve been in teaching for over 20 years, but it was only 5 or 6 years ago that I started having problems. Iām asthmatic, which probably doesnāt help, and classrooms arenāt as quiet as they used to be, so youāre raising your voice a lot of the time. On one occasion I lost my voice so badly that I had to pass a note to the doctor to explain what was wrong with me. I literally couldnāt say a word. The doctor just shook his head and said āSingers, actors and teachers; itās always the sameā.
I realized I needed to do something to save my voice, so I asked my headteacher about the possibility of some kind of microphone. Now I wear a headset, rather like the ones pop stars use, and speak into the mouthpiece in a normal voice. My voice is amplified through speakers that can be positioned wherever I want in the classroom.
Itās strange for a while, but then you forget youāre using it. Thereās a novelty factor for the pupils too, though again, they soon get used to it. The only problem was that a colleague got the same system at the same time, and until we got our frequencies sorted out, my voice kept coming through in her room and vice versa. Very confusing for everybody.
I started off using the system every day, but now my voice has recovered I rarely need it. In any case, since I started having voice trouble Iāve adjusted my teaching style and I donāt talk as much as I used to. I try to plan my lessons so there is some time for pupils to get on by themselves.
Most schools would benefit from a couple of microphones that can be shared when staff have problems. They cost a few hundred pounds: if someone is off sick because of vocal problems, the cost of supply will far outstrip that. Itās not a case of having one day off if you lose your voice; itās taken me two to three weeks to recover.
The long autumn term is definitely the worst time. Lots of colleagues are coughing, croaking or hoarse. You get people apologising in the staffroom for not being able to have a chat. And a serious problem, like nodules on the vocal cords, can threaten a whole career. The room where I teach has good acoustics, but when I cover lessons around the school I find some classrooms more difficult. If thereās any kind of echo you end up raising your voice to compete.
I look after my voice much more now. My consultant taught me the importance of keeping my voice hydrated. Every evening I hold my head over a bowl of steam and inhale ā you can feel the soothing effect on your vocal cords ā and Iām never without a bottle of water in school.
But why had I never been told this before? Thereās definitely a case for proper voice training for all teachers at college. Iām a county secretary for the National Association of Schoolmasters Union of Women Teachers (NASUWT) and, from a union perspective, schools are in breach of their duty of care if they donāt make sure employees know how to use their voice safely and effectively.
