Speech Synthesis (Text-to-Speech, TTS) technology transform the wording of an utterance into sounds that are outputted to the user.
Tilde has worked on Speech Synthesis technology development since the late 1990s. Technology for pronouncing Latvian words and texts is also included in our product Tildes Birojs.
In 2005, Tilde together with the Latvian Society of the Blind started a project to address the needs of visually impaired people using computers in Latvian. The architecture of the system covers the traditional TTS transformation, performing text normalization, grapheme-to-phoneme conversion, prosody generation, and waveform synthesis. Now it is available free of charge for all visually impaired people in Latvia.
