Cepstral TTS and SSML Support
Cepstral TTS offered support for Speech Synthesis Markup Language (SSML), a standardized way to control various aspects of speech synthesis. SSML allows developers to fine-tune the pronunciation, intonation, and style of synthesized speech, providing a greater level of customization. By incorporating SSML tags into their text, users could influence how the TTS engine vocalized the content. This enhanced control over speech output made Cepstral TTS more versatile and adaptable to different application requirements.
Common SSML tags supported by Cepstral TTS included <break> (pause), <voice> (voice selection), <prosody> (pitch, rate, volume adjustments), and <emphasis> (emphasis level). The <break> tag allowed users to insert pauses of varying duration and strength, improving the rhythm and flow of the speech. The <voice> tag enabled the selection of different voices, while <prosody> provided control over pitch, rate, and volume. Lastly, <emphasis> allowed users to emphasize certain words or phrases for better clarity.
