ASR for Disordered Speech


ASR For Disordered Speech

People with speech disorders often have physical disabilities which make it difficult to use normal keyboard-mouse interfaces.

For these people voice-driven interfaces are an attractive alternative even though speech production is limited.

Considered as an ASR problem,

  • There will be a small vocabulary of isolated words or short phrases,
  • Recognition will be speaker-dependent


  • there will be little data to train on (it’s often an effort to speak)
  • what data there is will be highly variable

The only way to  obtain more data is from a system which is in use

A new methodology for building personal recognisers is needed
