SSML
Speech Synthesis Markup Language, an XML-based markup language used to control speech output parameters of TTS systems such as speaking rate, pauses and stress.

Error handling for TTS streaming responses is more demanding: once the stream begins transmitting, the HTTP status code can no longer be changed, and errors can only be reported via logs or in-band signals.
In batch synthesis scenarios, ElevenLabs supports concatenating multiple lines of dialogue with SSML tags into a single request body, thereby completing the generation of multiple speech segments in one network round trip.
Different TTS vendors vary in their degree of support for SSML subsets, so before integration you should consult the vendor's documentation to confirm which tags are available.
SSML is an XML-based markup specification used to control pronunciation details in TTS requests, such as inserting pauses, adjusting speech rate and pitch, and specifying emphasis.
When cloning a voice, the model easily mispronounces out-of-vocabulary words; mitigation measures include: using SSML <phoneme> tags to provide phoneme annotations, fine-tuning the cloned model with a small dataset containing these words, and falling back to a generic voice for problematic segments.
SSML (Speech Synthesis Markup Language) is a speech synthesis markup language developed by the W3C that uses XML to describe how text should be read aloud, and mainstream TTS engines all support a subset of it.
Commonly used SSML tags include <break time="500ms"/> to control pauses, <prosody rate="slow" pitch="+2st"> to adjust speech rate and pitch, <say-as interpret-as="characters"> to read out letter by letter, and so on.
The core dimensions for evaluating TTS quality include voice naturalness, emotional expressiveness, multilingual and multi-accent support, and whether SSML markup is supported to control speed, pauses, and stress.
