AI Realtime Voice Chat
Speak with AI and Hear Instant Replies
Turn on your microphone and start talking — AI responds instantly with voice like a real friend, for English practice, academic and career advice, brainstorming and content creation. Type whenever you like, and get the answer from any of 20+ chat models.
What is Realtime Voice Chat and Why Do You Need It?
Realtime voice chat with AI is a cutting-edge technology that lets you talk to artificial intelligence like a real phone call. Simply press the live conversation button and start speaking — AI responds instantly with natural voice. Simultaneously, the full conversation transcript appears on screen, and you can also type text messages instead of speaking.
The live conversation runs on OpenAI's GPT Realtime voice models. They hear your voice directly and answer directly in voice, without turning what is said into text and back into speech first, so the conversation flows with only short pauses. There are two options: the full model for more careful conversations, and Mini, which is lighter and cheaper. For messages you type, or dictate with the microphone button, 20+ chat models are available: GPT from OpenAI, Claude from Anthropic, Gemini from Google, Grok from xAI, DeepSeek, and Perplexity for cited web search.
Key use cases include practicing English conversation with different accents, receiving voice consulting on academic and career topics, creative brainstorming for podcast and video content production, and preparing for job interviews. All your conversations are automatically saved and you can access your chat history at any time, edit conversation titles or delete old discussions.
To start your AI voice conversation, simply create a free account on DeepFA. With no software installation needed, you can begin voice chatting directly in your browser on mobile, tablet or desktop. You can also enable real-time data, so the AI uses up-to-date internet information when it answers typed messages.

What is AI Realtime Voice Chat and what is it used for?
From English language practice to voice consulting and brainstorming — everything you need to know about realtime voice conversation with AI.
AI Realtime Voice Chat is a groundbreaking technology that transforms the experience of talking to AI. Unlike traditional text chats where you need to type and read text replies, this method only requires you to turn on your microphone and speak — AI instantly responds with a natural voice, just like a real phone call. Simultaneously, the full conversation transcript appears on screen, and you can type text messages at any time instead of speaking. This capability is ideal for English language practice, voice consulting, brainstorming and any scenario needing fast, natural interaction.
The key difference from other similar services is that live voice and text chat sit side by side on one page. You talk on the GPT Realtime voice models, full or the cheaper Mini, and whenever you need to, you type a message and get its answer from one of 20+ chat models such as GPT, Claude, Gemini or DeepSeek. By enabling real-time data, the AI also uses up-to-date internet information when it answers typed messages. All your conversations are saved, and you can search through history, rename titles or delete them.
Voice Chat vs. Text Chat — What is the fundamental difference?
In text chat, you must type and read replies — slower and less natural. In realtime voice chat, you speak and hear voice responses, just like a real phone call. The conversation transcript appears on screen simultaneously, and you can combine both methods.
Which model is right for you?
Live talk: GPT Realtime Mini is enough for language practice and everyday conversation, and cheaper; the full GPT Realtime suits more careful conversations. Typed messages: GPT is all-round, Claude writes and analyses carefully, Gemini handles long texts, DeepSeek reasons at low cost, Grok is witty, and Perplexity answers from the web with sources.
Speech to speech — smooth, natural experience
The GPT Realtime voice models hear your voice directly and answer directly in voice, without turning what is said into text and back into speech first. That keeps the pause between your words and the reply short, so the conversation moves like talking to a real person.
English Language Practice — Best tool for accent and pronunciation
Speak with AI like a native English speaker partner. Practice different accents (American, British), improve pronunciation, learn everyday expressions and get instant feedback. Voice chat is far more effective for this than text chat.
Auto-save and complete history — never lose a conversation
All your voice conversations are automatically saved. Search through history, rename conversation titles or delete old ones. Search within past conversations also helps you quickly find important ideas and information.
