Add Edge TTS generic output module

[Jyatin]

Summary

Adds an initial generic output module configuration for using Microsoft Edge TTS with Speech Dispatcher.

Changes

• Add config/modules/edgetts-generic.conf
  • Adds support for en-US, hi-IN, bn-IN, and gu-IN
  • Adds several Edge TTS neural voices
  • Configures the generic module to invoke an Edge TTS wrapper
• Change the generic module shell from /bin/sh to /bin/bash
  • Required because the generic module currently executes commands using set -o pipefail
  • /bin/sh resolves to dash on the tested WSL environment, which does not support pipefail

Testing

Tested locally on WSL2 with Speech Dispatcher and Edge TTS.

Verified that:

• Speech Dispatcher invokes the generic module.
• The Edge TTS wrapper is invoked successfully.
• Edge TTS generates an MP3 file.
• Audio playback works successfully.

Thanks for this, just a few fixes are needed.

Please add copyright information, like other .conf files

is speechd-edge-wrapper really supposed to be in /root/bin??

Also, please use GenericCmdDependency to make sure to automatically disable the module when the command is not available.

Are all voices always available, or does that depend on the existence of a file? If the latter, please use VoiceFileDependency so that voices are shown to the user only when available.

Also what provides this speechd-edge-wrapper? I searched online and couldn't find anything.

Thanks for the review. I’ve addressed the requested changes:

Added copyright information to the configuration.
Replaced the unavailable speechd-edge-wrapper with the edge-tts command directly.
Added GenericCmdDependency "edge-tts" so the module is disabled when the command is unavailable.
Verified the configuration locally and confirmed that Edge TTS successfully generates audio.

Please let me know if any further changes are needed.

he Edge TTS voices are provided by the online Edge TTS service and do not depend on local voice files, so VoiceFileDependency is not applicable here. GenericCmdDependency "edge-tts" ensures that the module is disabled when the edge-tts command is unavailable.
