Text-to-Speech
Enhance your text-to-speech (TTS) system with linguistically informed, expertly structured data that improves accuracy, naturalness, and user experience across languages and domains.
Linguistic intelligence that powers natural-sounding speech
Text-to-speech systems are only as good as the language data behind them. Oxford Languages provides rich, structured linguistic resources that improve pronunciation, stress placement, rhythm, and intelligibility — helping TTS engines produce speech that sounds more natural, more accurate, and more human.
Our solutions combine deep lexical insight with scalable datasets designed specifically for speech technologies.
