Can I use voice with GPT-5 and Claude?

Yes. Multio routes voice prompts to whichever model the chat is set to. Latency varies by model — flagships take longer to respond than fast tiers.

Does voice input work in any language?

Most major languages are supported via the underlying transcription. Quality varies — English, Spanish, French, German, Mandarin, and Japanese are strongest.

Best models for voice chat

Model	Why it wins for voice chat

Multio runs all of these in one chat — switch between them mid-thread without losing context.

Sample prompts to copy

Tested starting points for voice chat on Multio. Copy, paste, edit to fit your task.

Hey, I am brainstorming a name for a coffee shop. Throw me 10 ideas — playful, not generic.
Quick question — explain quantum entanglement to me like I am a smart 12-year-old.
I am driving and need a recipe for what is in my fridge: eggs, kale, leftover rice. Walk me through it.
Help me prep for a tough conversation. Pretend you are my report and push back on what I am about to say.

Step-by-step workflow

Tap the mic and speak. Voice input transcribes locally and sends to whichever model is selected.
Pick a fast model. Voice exchange feels broken when the model takes 8 seconds to start. Pick Mini, Haiku, or Flash for sub-second first tokens.
Keep prompts short. Voice prompts work better when they are direct. Save complex briefs for typed chat.
Switch to text for long content. Voice is great for quick exchange; text is better for code, formatting, or long output.

Common pitfalls — and how Multio handles them

Long latency breaks the feel
Stick to fast models. Opus or GPT-5 over voice is painful; Haiku or Mini feels right.
Misheard prompts
Speak in short complete sentences. Punctuation in your speech improves transcription.
