Text-to-Speech
Hear translations spoken aloud
Click the speaker icon next to a translation to hear it. Two engines are available: browser-native (free, always works) and AI voices (Pro/Team, higher quality).
Browser TTS (free)
Uses your operating system's built-in voices. Works for all 100+ languages SwiftIn supports. Quality varies by OS — generally fine for understanding pronunciation.
AI voices (Pro/Team)
Higher-quality, more natural voices powered by AI. Pick male or female voice. 1K TTS tokens / month for Free, 50K for Pro, 50K per seat for Team.
Auto-fallback
When AI TTS quota runs out, SwiftIn quietly falls back to browser TTS. You're never stuck without audio.
