I usually test voices based on the use case first appointment setter, support, receptionist, sales, etc. Not every good voice fits every workflow. 11Labs is solid and one of the best for natural sounding voices, but I also compare options like OpenAI, Cartesia, PlayHT, and Rime depending on latency, realism, and pricing. Best approach is to test 3–5 voices with the same script and see which sounds most human for your audience. I can help you compare and pick the right one for your AI agent setup if you want. @Laurent
