Vapi helps developers build, test, and deploy voice agents at scale. We enable everything in between the raw models and production, including telephony, test suites, and real-time analytics.
As of the latest updates, there is no documented feature for adjusting playback speed specifically for call logs within the Vapi platform. The speed controls mentioned in the recent updates pertain to voice synthesis and call handling.
For adjusting voice speed in synthesized outputs or call transfers, you can refer to speed settings in features like Eleven Labs Voice or CartesiaExperimentalControls here.
If you have any further information or changes since the latest documentation, I recommend checking the platform for any new updates regarding playback speed capabilities. Let us know how we can help further.
