Weird PAUSE in the middle of the TTS audio

[abidhasanpintu]

I am using deepgram tts api to generate audio from text. But we are getting some weird PAUSE in the middle of the audio. We don't find any solution for that issue by looking at api docs. Can anyone check the attached audio and suggest what's the issue?

In the following audio after "on" a pause/break happens. I have used aura-stella-en voice

@abidhasanpintu have you tried setting the container param yet? https://developers.deepgram.com/docs/tts-container. It can sometimes help with playback issues.

@jpvajda Thanks for your response. We have tried container. But problem is, when we use container, we get bip/click sound at the beginning of the audio
