Voice output communication aids
Voice output communication aids in this section use electronically stored speech as a means of communication. The speech output may use digitised speech, synthesised speech or both. Digitised messages are created by recording spoken words directly into a communication aid. Users can record words or messages that aren't in a synthesised vocabulary. Synthesised speech is artificial, computer-generated speech. The quality of the synthesiser speech is far better than it used to be. Sentences or longer messages can be strung together from individual words or phrases and the vocabulary can contain several thousand words. Software based computer equipment is not generally listed in DLF Data, refer instead to organisations such as AbilityNet and ACE Centre. It is recommended that a Professional holding a Speech and Language Therapy (SALT) qualification, should be consulted before purchasing a communication device.
