Text-to-Speech

Text-to-Speech (TTS) is the technology that produces spoken audio from written text — synonymous with speech synthesis but emphasizing the input-output direction. Modern TTS quality is so high that synthetic speech is often indistinguishable from human recordings, transforming applications across accessibility, media production, and conversational AI. Major TTS providers include OpenAI (six voice options for chat assistants), ElevenLabs (often considered highest-quality with extensive voice cloning), AWS Polly, Google Cloud TTS, Microsoft Azure Speech, Resemble AI, PlayHT, and open-source options like Coqui XTTS, Tortoise TTS, Bark, and the speech capabilities in GPT-4o, Gemini, and other multimodal LLMs. Real-world deployments include consumer voice assistants (Siri, Alexa), in-car navigation voices, accessibility readers for visually-impaired users, audiobook production at scale, IVR systems for customer support, podcast automation, voice-enabled chatbots, and increasingly the audio output of conversational AI like ChatGPT Voice and Claude. AI governance, AI compliance, and AI risk management programs deploy TTS with consent and disclosure controls — supporting responsible AI through transparent voice generation in enterprise AI environments worldwide.
