SSML Parsing not being enabled
# support
j
Hello team, I'm trying to enable SSML parsing for my agent, but it doesn't seem to work, even though I have attempted to patch it via api with a 200 request response, it still doesn't work and the agent does not comply with break tags. Instead, it spells out the tags out loud rather than implementing the actual pauses. I've tried running the patch request with the structure shown in the photo, however it's still not working properly, despite getting a 200 response. When running a get request via the API, the "enableSsmlParsing variable is not present, which indicates that it was not successfully enabled. In the call logs, it's shown in the attributes that SSML parsing is set to false, which indicates that the issue is with vapi not with elevenlabs. Much appreciated! https://cdn.discordapp.com/attachments/1426099381001519165/1426099381379272796/Screenshot_2025-10-09_at_11.20.08.png?ex=68e9fe0c&is=68e8ac8c&hm=0c06304ef1be03bd57115d49c9a0853bb07b2037e2ca51f2f7fb180c12025004& https://cdn.discordapp.com/attachments/1426099381001519165/1426099381668544563/Screenshot_2025-10-09_at_11.23.41.png?ex=68e9fe0c&is=68e8ac8c&hm=e135b0317293de012f220a5bc640f4367730433cd9c783a69fbb7414cde495b0&

Hey, I can help you get SSML parsing to work properly. It sounds like the issue is with Vapi not persisting the enableSsmlParsing flag even after a successful patch. I can check how your agent’s config is being updated and make sure the setting is applied correctly at runtime. Usually, this happens when the patch is made at the wrong level or not saved to the active voice profile. Could you confirm if you’re applying it at the agent level or directly in the assistant’s voice config? @Johnny17

I'm applying it to the agent level I believe via the api request, I can't find an option to enable it in the voice settings in the UI

Yeah, that makes sense. If you’re setting it at the agent level, it’s likely the API isn’t saving the config properly, which is why SSML isn’t kicking in. There’s a specific way to make sure the flag actually sticks even though it doesn’t show up in the UI. I’ve dealt with this before and can help you sort it out. Message me privately so we can look into it together @Johnny17

once you've figured it out, it would be appreciated if you provide more specific instructions on how to persist the setting.

Could you please provide your assistant id?
