  to eventually improve the prounounciation and replace it with the new sentence.
• add builtin voice list of xttsv2
• add czhech, croation and others with cv/vits
• add music interlude between chapters
• adding chapters name (if chapters well detected) in place of number in the final metadata
• split the output in multiple file if > 12hours # chapters as final
• installation of the right torch and cuda version if GPU available so deepspeed can be used
• automatic user crash bug report by email via a URL request
• create a legends.py file for all gradio/gui legends to manage multilanguage
• mark each sentence number in the metadata with the timeecode so
  the user would be able to re-convert one sentence before to export the audiobook
  (it requires to not delete the ebook temp folder)
• use websocat in cmd and sh script to connect in headless mode via gradio and avoid tts load at each command
