12 AI live translation tools compared on latency, languages and pricing

Key points

• Palabra.ai claims under 1 second latency and charges $0.04 per minute for API speech-to-speech translation.
• Google says Gemini 3.5 Live Translate covers 70+ languages but runs a few seconds behind the speaker.
• Apple's Live Translation runs entirely on device with 10 language variants, requiring recent AirPods and iOS 26.
• Teams Interpreter's language count is listed as 9 in admin docs and 10 on the support page.

Why it matters for marketers: Content teams planning multilingual calls or webinars should compare latency and per-minute cost, then pilot on their own language pairs, since counts aren't directly comparable.
