Text to speech has different audio qualities

[zoomshoes]

Hi all, I have noticed in contact center the text to speech has different audio qualities. The text to speech created in the flow is different to that created in the assets library used on the queue. It is quite noticeable when the voice swaps between the flow and the queue audio. I don't suppose there is a work around for this, I really would like it to sound like one continues voice talking.
