ElevenLabs — Multilingual V1 Text-to-Speech

Multilingual V1 turns text into natural, expressive speech across multiple languages. It delivers clean pronunciation, smooth pacing, and controllable tone—great for voiceovers, narrations, learning content, and product videos.

🎧 Key Features

• Multilingual synthesis with automatic accent handling
• Humanlike intonation and timing; clear number/date reading
• Tone controls via similarity and stability
• Speaker boost for crisper English numerals and units
• Large built-in voice library (see the voice list)

💰 Pricing

• $0.10 per 1,000 characters
• If the input length is less than 1000 characters, it will be counted as 1000 characters to pay.

🚀 How to Use

1. Enter your text in the text field.
2. Set voice_id to a built-in voice name (for example: Callum, Alice, Elli). For more options, use the voice list above.
3. Optional controls • similarity: 0–1 (higher = closer to the base voice’s timbre) • stability: 0–1 (higher = more consistent delivery) • use_speaker_boost: improves English number and unit reading
4. Click Run to generate and preview your audio.

📝 Notes

• Works best with clear punctuation and short sentences; split very long text into segments.
• voice_id must match a valid ID, if you see an invalid-voice error, pick one from the voice list.
• use_speaker_boost is especially helpful for English financial, time, and measurement reads.
