SSML
Last updated: 2025-01-23 17:40:00
Speech Synthesis Markup Language (SSML) is based on XML to define the effects of synthetic speeches more accurately and specifically.
Note:
Tencent TTS implements SSML based on Speech Synthesis Markup Language (SSML) Version 1.1.
Currently, the SSML feature is supported only for Chinese.
Directions
The tagged text is uploaded to TTS as the value of the
text parameter. Below is the content of the request sent to TTS:{"Action" : "TextToVoice","AppId" : 12345,"Codec" : "mp3","Expired" : 1603271036,"ModelType" : 1,"PrimaryLanguage" : 1,"ProjectId" : 0,"SampleRate" : 8000,"SecretId" : "AKID****","SessionId" : "1234","Speed" : 0,"Text" : "<speak>The mobile number is <say-as interpret-as=\"telephone\">4008110510</say-as>.</speak>","Timestamp" : 1603184636,"VoiceType" : 1002,"Volume" : 5}
TTS supports SSML tags. Here, text in undefined
<speak> tags will not be synthesized, and an incorrect XML format may interrupt synthesizing the text in <speak> tags.The SSML feature of TTS supports nesting multiple
<speak> tags in the text; for example:<speak>Her name is <say-as interpret-as="name">Ren Yingying</say-as>.Her mobile number is <say-as interpret-as="telephone">+86-15188888888</say-as>.She is <say-as interpret-as="cardinal">22</say-as> years old.She has a package with the tracking number <say-as interpret-as="digits">5648234514237588</say-as>.Her address is <say-as interpret-as="address">304, Unit 3, No. 10,000, Shennan Boulevard</say-as>.</speak>By the way,<speak>Her username is <say-as interpret-as="characters">b888_uαβγ</say-as>.</speak>
