Welcome to the Convai Developer Forum!

Thank you for reaching out. Unfortunately, we do not have any specific customizations or solutions for this issue, and we haven’t been able to reproduce it on our end.

I recommend checking the audio settings within Unreal Engine to ensure they are configured correctly for your project. This might include adjusting the volume multiplier, spatialization settings, or other audio parameters that could impact output levels on iOS devices.

thanks.

Does this mean that this is a known problem or a setting issue that only appears for me? Is there an easy way to increase the volume? If so, I would do that, i.e. generally just have everything output louder. Many thanks for your help.

No, this does not appear to be a known issue, and we have not been able to reproduce it on our side. It may be related to your specific settings or setup.

To address this, I recommend checking Unreal Engine’s audio settings and exploring guides available online.

Additionally, I recommend testing your character directly on convai.com to check the audio. This can help determine if the issue is related to your project or the voice.

You might also try using a different voice to see if it makes a difference in the volume levels.

I use a custome elevenlabs voice and it sounds very well on android devices. On ios devices too, but very quiet. So i will try to change the volume min max input in the convaibasecharacter BP.

thanks for your help
