16khz output from indic voice

[MittalShruti]

Hello, I am using indic voice to generate the audio

./flite/bin/flite "-voice" flite/voices/cmu_indic_hin_ab.flitevox 'पुत्र मित्र आदि सगे संबंधियों' "-o" 'try.wav'

The output file try.wav is always 16khz. However, in the README.md it was mentioned that the output is deliberately kept at 8khz. Is it not valid for non-us voices?

That is strange.

It appears the included slt voice also produces a 16kHz WAV file:

Hi Shruti,

Can you share the cmu_indic_hin_ab.flitevox file please ?

I'm not the original issue reporter, but I believe they used the voices provided on the associated website, specifically:

http://www.festvox.org/flite/packed/flite-2.1/voices/cmu_indic_hin_ab.flitevox

I was able to recreate the issue:

flite -voice "http://www.festvox.org/flite/packed/flite-2.1/voices/cmu_indic_hin_ab.flitevox" 'पुत्र मित्र आदि सगे संबंधियों' -o try.wav

This file appears to have a 16KHz sample rate:

aplay --samples=1 --verbose try.wav

which gives
