Optimizing Speech Synthesis Quality with Speech Synthesis Markup Language (SSML)

Speech Synthesis Markup Language (SSML) is a markup language used to control factors such as pauses, volume, pitch, speech rate, and pronunciation of nouns in speech synthesis. This language, standardized by the World Wide Web Consortium (W3C) with XML as its foundation, is widely supported by many online speech synthesis services. Providers such as Google Cloud, AWS, Alibaba Cloud, among others, offer speech synthesis services that support SSML. Compared to text-to-speech (TTS) tasks performed using plain text, utilizing SSML allows for finer control over the synthesis of speech, thereby optimizing the quality of speech synthesis.
