Multilingual TTS AI Supporting 50+ Languages
Multilingual TTS AI on Flixly supports 50+ languages with Gemini 3.1 Flash TTS. Generate consistent natural voices for video and audio projects without hiring multiple actors.
TL;DR
Flixly's text to speech tool uses Gemini 3.1 Flash TTS to deliver natural audio in 52 languages. Users pay 1.2 credits per minute, receive 48 kHz files in seconds, and maintain the same voice profile across languages. The workflow replaces separate hires and keeps timing consistent for global video projects.
The daily cost of language limits
A creator needs a 90-second product video narrated in Spanish, Japanese, and Arabic by Friday. Hiring three voice actors runs $450 and takes four days. The usual fix of machine translation plus stock TTS produces flat delivery that drops watch time by 30 percent.
Why generic TTS tools fall short
Most platforms handle five or six languages at usable quality. Switching models mid-project breaks consistency in tone and timing. Gemini 3.1 Flash TTS inside Flixly keeps the same voice profile across languages because the model was trained on aligned multilingual data.
How Flixly handles 50+ languages in practice
Users open the Text to Speech page, paste the script, and select the target language. The system returns a 48 kHz WAV in under 12 seconds for 200 words. Credit cost sits at 1.2 per minute of audio. The same workflow works for Korean, Hindi, and Swahili without separate accounts.

Edge cases and real limits
Names and technical terms sometimes need phonetic spelling. The interface accepts SSML tags for emphasis and pauses. Output files stay under 25 MB for direct import into Video to Video or Lip Sync Video.
Long scripts over 1,200 words benefit from batch mode. Each chunk keeps the same speaker ID so the final edit sounds continuous.
Adding voice cloning for brand consistency
Record a 90-second reference once. The cloned voice then works in any supported language. This step lives in the Voice Cloning tool and costs 8 credits per clone.
Pairing audio with visuals
After generating speech, drop the file into Music Generation for background layers or Text to Video for synced animation. All tools share the same credit wallet.
