Known specifics

data is a dictionary object, not an array. To iterate over all voices, use Object.entries(data). To get a specific voice by identifier: data['ruinternalfemale'].

Default voice. If the voice parameter is omitted in an automatic call, Bitrix24 selects the default voice based on the Bitrix24 account language. For a Russian-language account it is ruinternalfemale.

The set of voices depends on the plan. The available voices and their identifiers may differ depending on the Bitrix24 account plan.
