call id 4bcbe8fc-8a6f-4d63-9322-40edaa491324 speed, tone and volume sound quite different for the following messages. This produce a very bad experience and the system is not predictable https://cdn.discordapp.com/attachments/1367814589407952936/1367814590213128263/image.png?ex=6815f41b&is=6814a29b&hm=5aebd321364d6ccbba23ca7376cc7239d577adf88cb4022ebb478907d295bc10&

This is likely a caching issue with the voice provider. According to the information I found, voice providers like 11Labs use caching mechanisms that can cause inconsistencies in the first message:

// Try this solution
// Change your first message slightly to force a new cache entry
const firstMessage = "Hola, soy Carlota, asistente virtual de AR Motors. Recibimos una solicitud sobre un Kia. ¿Es correcto?";

Making a small change to your first message text can force the creation of a new cache entry and potentially resolve the inconsistency.

Even with cacheEnabled = false set in the voice settings, the pronunciation is quite different.

Hey! To help track down this issue, could you share: - When exactly this happened (the timestamp) - What response you expected to get - What response you actually got instead This would really help us figure out what went wrong!

thank you @Shubham Bajaj if you see the sound waves it is easy to understand that the sound is different. Thank you for your appreciated help

Hey David, if it worked for you, could you try the same call with 11labs instead?

We don't have this problem with 11labs, but we're looking for alternatives to avoid working with a single supplier. Call ID with 11labs: cd732632-4b18-4412-8fc4-72369efc9aac

David, I understand your concern. If a provider experiences an outage, you can easily switch to another one. It is always prudent to test alternative providers in advance to ensure a reliable solution. I recommend continuing to utilize our VAPI Voices, Azure, and Cartesia services. While caching may occasionally occur on these platform, it is not a consistent issue.
