There are a variety of symptoms associated with functional dysphonia and these differ from person to person. However, those listed below are fairly typical. Of course, you don’t have to experience each one of these to be experiencing a functional voice difficulty.
- hoarseness, huskiness, roughness or breathiness
- voice is too deep or too high
- pitch range is more restricted
- voice is variable and deteriorates with use
- voice may ‘go’ altogether
- difficulty making yourself heard (see loudness)
- having to work quite hard to produce voice
- throat feels dry and sore
- breathing is a little uncoordinated

“It’s just the way I’m built”
Just as some people are natural athletes and others aren’t, some people’s voice boxes are better able to perform certain vocal tasks than others: everyone has their own limitations.
This can make a functional voice difficulty worse. The effect varies from person to person and depends on your personality type: some people are more extrovert than others; some people cope better with stress than others.
Poor vocal technique
Most people cope with a poor vocal technique for short periods of increased vocal demands, as long as they have enough time to recover. However, if the vocal demands continue for too long, or are too intense, this can lead to difficulties.
Exposure to dust, fumes, chemical agents and smoke – as well as smoking yourself – can all lead to difficulties. Acid reflux (heartburn), certain medications and allergies may also affect the vocal folds.
Whilst not strictly a primary cause, it is not uncommon for people to experience functional voice difficulties following a heavy cold or flu, and laryngitis.
