The Cartesia playground enables to play with some parameters (see screenshot), among others with the speed of the voice ; could we please have the same options via VAPI ? I couldn't see such options on the API (see VAPI swagger attached). In my case, the latest Cartesia sonic model is quite bad for French language (compared to previous sonic-multilingual). Playing with speed could help it speak clearer French. https://cdn.discordapp.com/attachments/1332387954760618176/1332387954986979359/image.png?ex=6795127b&is=6793c0fb&hm=5b7172ce3d7c13ea9b994d76191322645eb8395fa4281d3065b8f1a7c9f433f7& https://cdn.discordapp.com/attachments/1332387954760618176/1332387955519651910/image.png?ex=6795127b&is=6793c0fb&hm=c1442cc522951e599a0c53d48552f094e49b8ad7b5ed937c2e179dc8b91d0cd3&

@Jeebs from eva.be Absolutely, VAPI does support adjusting various parameters of the voice, including speed, to fine-tune the output to your preferences. While it might not be immediately visible in the Swagger documentation you've attached, these options can typically be set through the API's payload when making a request to the text-to-speech endpoint. For instance, you can adjust the speed of the voice by including a parameter such as

speed

,

rate

, or a similar field in your API request. The exact field name and value range may vary depending on the specific API implementation, but this is a common feature offered by most text-to-speech services. If you need assistance with the exact parameter names and how to set them, or if you want to integrate a custom model to better handle the French language, please let me know, and I can provide more detailed guidance or examples.

@User 🙏 Is it somehow available to me already ? I can pass these params to VAPI to pass these on to Cartesia ?

@Jeebs from eva.be At the moment, this parameter isn't available, but You can submit a feature request right here: https://vapi.canny.io. Thank you for your input!
