What is text-to-speech?

Modern neural voices come remarkably close — natural pacing, breaths, and intonation rather than the flat robotic tone of older systems. Short exchanges can be hard to distinguish from a person, though long or unusual conversations may still give it away. That realism is why responsible deployments disclose that the caller is speaking with an assistant.

Yes. Text-to-speech providers offer libraries of voices spanning gender, age, accent, and tone, and most phone AI platforms let you pick from a curated set and preview them. Choose one that fits how your business already sounds — a spa and a law firm probably want different voices. The voice becomes part of your brand's first impression.

Because silence is awkward on the phone. If the system takes too long to start speaking, callers assume the line dropped, talk over the assistant, or hang up. Modern systems use streaming synthesis — beginning to speak while the rest of the sentence is still being generated — to keep response gaps short enough that the conversation feels natural.
