Text-to-speech API: Pitch setting does not work for Greek

[Vikto__9494_]

Hi,

We use the Google Text-to-Speech API to generate voices for dialogues with different roles. Each role has a different pitch.

For most languages, like Hebrew or Norwegian, it works well. However, for Greek ("el-GR"), the pitch does not change anything.

It seems to be an issue with the API because, in the console simulator, pitch adjustments for Greek work correctly. (https://console.cloud.google.com/speech/text-to-speech;input=κοινός;locale=el-GR;voice=el-GR-Standar...)

Could you please check if this is a known issue or suggest a solution?

The same problem is found for Italian. Pitches setting also does not work in paid API

Hi Vikto__9494_,

Welcome to the Google Cloud Community!

All supported voices in the Cloud Text-to-Speech API should allow pitch adjustment and there are currently no known outages impacting this functionality. With this, I suggest filing a bug report so our engineering team can check whether this is a potential bug or project-specific issue only. Before filing, please check this documentation on what to expect after you've opened an issue.
