Speech Synthesis (Text-to-Speech, TTS) technology is employed for transforming the wording of that utterance into sounds that will be outputted to the user. Tilde has experience in Speech Synthesis technology development since late 1990's. Possibility to pronounce Latvian words and texts is also included in our product Tildes Birojs since 2002. In 2005, Tilde together with the Latvian Society of the Blind started a project with the primary goal of addressing 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 to anyone visually impaired in Latvia for free. |
