ViaVoice text-to-speech (TTS) technology uses the latest in linguistic technologies to synthesize speech. More than just a simple reader, ViaVoice TTS is a sophisticated technology that goes through several high level linguistic stages to create highly intelligible speech output. Rather than using small snippets of actual spoken recordings and gluing them together, the formant technology takes advantage of a synthesizer to generate the final sounds that we hear. The attributes of this technology are that it is highly intelligible, and, because it is totally generated by the computer, is very flexible and requires fewer system resources. It can accommodate an unlimited number of voices by modifying the gender, pitch, headsize, roughness, etc., and all of these attributes can be modified on the fly.
