Choosing a model: use cases and limitations

GPT Live 1

Choose it if… you want conversations with spontaneous interruptions and corrections.

What you can adjust here: Listening cues, patience during pauses, tone and formality. Style and pauses guide behaviour through instructions.

Worth knowing: Listening cues and pauses are guidance, not guaranteed frequencies. Listening cues such as “mm-hm” do not confirm bookings or other actions. Interrupting speech does not automatically cancel a tool that has already started.

A scenario to try: Request a Tuesday appointment, then interrupt with “No, Thursday”. Check that it accepts the correction before confirming.

GPT Realtime

Choose it if… you want to adjust pauses, interruptions and speed.

What you can adjust here: Speaking speed, silence duration or turn endings based on sentence meaning. Tone and formality too.

Worth knowing: Continuous listening is available with GPT Live.

A scenario to try: Dictate a number with a pause halfway through. Check that it waits, then try correcting it while it answers.

Gemini Live

Good to know: With Gemini you also choose the platform. Gemini Stable is recommended for phone calls and keeps data in Europe; Gemini 3.8 is the newer model, but on the phone it can misunderstand short sentences.

Choose it if… you want to give customers time to think and explain.

What you can adjust here: Silence duration, response variation, tone and formality. A candidate to try for detailed requests and explanations.

Worth knowing: Numeric speaking speed cannot be adjusted here.

A scenario to try: Explain a problem, pause for two seconds, then add a detail. Does it let you finish? Try a follow-up question too.

Eleven v3 Conversational

Choose it if… you want to find a voice that fits your business.

What you can adjust here: Tone, formality and response variation. Listen to several voices saying the same greeting to find the right character.

Worth knowing: Not all provider expressiveness features are available here.

A scenario to try: Ask two voices to deliver the same welcome and respond to an unhappy customer. Assess clarity, warmth and fit with your business.

Nova Sonic

Choose it if… you want to welcome customers in the seven supported languages.

What you can adjust here: Style and response variation. Polyglot voices can retain their vocal identity across supported languages.

Worth knowing: Arabic and Chinese excluded; speed and pauses cannot be adjusted here.

A scenario to try: Start a request in Italian, then continue in English. Check that it retains the details and that pronunciation suits your customers.

Grok Voice Think Fast 2.0
