About
OpenAI’s TTS models are less expressive than ElevenLabs at the top end but introduce a genuinely useful idea: you instruct the delivery in natural language ("warm, unhurried, like you are explaining to a nervous candidate"). For screening flows where tone should shift with context, that is easier to control than a fixed voice preset.
