Which AI chatbots support voice features: how to speak and listen

AI chatbots are making voice the new normal.

Over the course of 2025, voice communication with chatbots and AI assistants has become one of the most sought-after and widespread interaction modes. Talking to an artificial intelligence and listening to synthesized, real-time responses is no longer just a technological curiosity, but an everyday experience that accompanies work, personal life, and even social interactions. Major platforms, each with their own approach and level of maturity, have invested in integrating voice as both input and output, offering users increasing naturalness and ever more sophisticated functionality.

ChatGPT expands interaction possibilities with natural voice.

OpenAI’s ChatGPT now stands out for having one of the most advanced voice systems in the sector, able to interpret spoken language in more than fifty languages and deliver fluid, contextual, and customizable responses. The built-in microphone on mobile apps and, more recently, on the web desktop portal allows you to start conversations simply by speaking. Users can choose among five different voices for output, receiving more expressive and believable answers that adapt to various contexts. The latest developments in 2025 include simultaneous multilingual translation, better recognition of emotional nuances, and more continuous conversations without having to repeat instructions or voice activations. ChatGPT is therefore ideal not only for textual chatting but also as a genuine conversational personal assistant.

Commands can be given hands-free, responses arrive in moments, and the assistant adapts to the user’s tone, habits, and preferences. Voice personalization is still in development, but Alexa+ already offers one of the most immersive experiences for smart home control and daily task management.

Siri evolves with Apple Intelligence and defends voice privacy.

The integration of Apple Intelligence has revolutionized Siri, which now uses LLM models directly on-device, without sending voice recordings to Apple’s servers. This allows management of complex requests, simultaneous translations, suggestions, and advanced voice notifications more quickly and privately. Siri can converse in multiple languages, recognize request contexts, and adapt its voice generatively. Privacy focus is central: all voice processing happens locally, and the user can decide which data to share or delete.

Siri + Apple Intelligence Strengths

Key Element	Detail
Local processing	All on-device, no cloud
Privacy	Full user control
Live translations	Calls and multilingual conversations
Voice	New TTS engine, natural and contextual
