Voice list needs to be organized

[ari-os310]

Currently, the menu bar toggles open to a list of voices that comes from the Text-to-Speech API. The voices are rendered without any order or organization. This issue intends to:

• sort voices by language starting at English

• create clear dividers between each language

For example:
English
en-US_LisaV2Voice
en-US_MicahelV3Voice
en-US_HenryV3Voice
French
fr-FR-ReneeV3Voice
fr-FR-ReneeVoice
Italian
it-IT_FrancescaVoice

...and so on.
