How to list speaker_id from pre-trained multi-speaker TTS model?

[arthurwu4work]

Hi,

How to list speaker_id from pre-trained multi-speaker TTS nemo model ?

I used the tts_en_fastpitch_multispeaker.nemo
the document (here) say this model have 10 speakers
but the speaker_id is not 0-9

and in the NGC (here) The speaker IDs go from 1 to 20.

I tried to use range(30) to generate audio from speaker_id 0-29
It works sucessfully, why ?
( a lot of them just sound the same. )

where can I know what is the correct speaker_id ?

All I could find out was list_available_model()
Is it possible to list available speaker_id from pre-trained multi-speaker TTS nemo model ?

thank you
