Products.
VoiceText speech synthesis is the NeoSpeech software component that generates synthesized speech from input text. NeoSpeech uses Unit Selection Synthesis (USS), which utilizes large databases of recorded sound segments to create synthesized speech. The VoiceText TTS Engine is mainly used to build custom stand-alone TTS applications such as AAC (Augmentative and alternative communication) products, gaming software, automated loud speaker/paging systems, educational software, and language learning apps. It also can be used simply to output a voice from an input text using a provided desktop TTS program.
