This advice sheet has been produced to provide you with information about how to correctly use you artificial larynx. It is not meant to replace discussion between you and your doctor. If, after reading it, you require further explanation please discuss this with the relevant person who has been caring for you.
There are two types of artificial larynx (electrolarynx) available:
- Intra-oral: Has a tube attachment that is placed in the mouth
- Neck: Placed on the neck or cheek
It is important to consider the following points when using these aids:
Placement: Correct placement of the aid in the mouth or on the neck/cheek is essential for success. When using an intra-oral aid, the tube should be inserted about 1-2 inches inside the mouth, ensuring minimal obstruction to the tongue and teeth. When using on the neck or cheek, a soft, pliable area of skin is required, large enough to place the head of the aid comfortably. Do not use on a spot that triggers coughing or discomfort.
On/Off timing: This is essential in order to avoid unnecessary or obtrusive noise. Switch on only as speech movements are initiated and switch off as soon as your message is complete. It may help to slow down your speech rate slightly.
Phrasing: Try to use a natural speaking rhythm with pauses, as in normal conversation.
Loudness: You will need to adjust the volume for quiet and noisy situations. Reduce the volume when on the telephone.
Articulation: You may need to emphasize speech sounds to improve clarity. Please refer to the practice items.
Intonation: Try to introduce variations and interest into speech. It may help to practise telling a joke, where changes in tone are required.
Exercises to aid clearer speech when using an artificial larynx:
- Open your mouth as if saying “ah”
- Repeat “mah”, “mah”
- Count 1-10
- Recite the days of the week
- Recite the months of the year
- Practise the lists of similar sounding words
- Practise short social phrases eg:
- Hello, how are you?
- Fine thanks
- That’s nice
- See you soon
Practise this list of similar sounding words, emphasizing the difference between them:
am/an all/ or on /ale aim /aid
eye /isle owe /ore we /wear wore / why
low / lay law /lee lame / lane lone / load
me /may more / my knee / know nor / name
pie/buy too/do tuck/duck cut/gut

chill/Jill chess/Jess chain/Jane chin/gin
lie/rye late/rate lack/rack lamp/ramp
pay/play bite/bright tick/trick core/claw
gate/grate four/floor sell/spell sick/stick
Please return the aid if it develops any faults. Please do not attempt any home repairs, as this may invalidate the warranty. Avoid over-tightening the top or base as this will lead to cracking. To prevent the unit hitting a hard surface, please use the neck cord or carry case.
