The W3C does have a standard for speech synthesis markup called "Speech Synthesis Markup Language" (SSML): https://www.w3.org/TR/speech-synthesis11/ https://www.w3.org/TR/speech-synthesis11/
Whether it's supported by a particular speech synthesis system and which set of features are supported varies.
The standard does include a section on "3.2 Prosody and Style" which covers this aspect to some degree: https://www.w3.org/TR/speech-synthesis11/#S3.2 https://www.w3.org/TR/speech-synthesis11/#S3.2
