ElevenLabs — Flash V2 Text-to-Speech

Flash V2 turns written text into natural-sounding speech with crisp pronunciation, smooth pacing, and expressive tone—ideal for voiceovers, narration, tutorials, podcasts, and digital content. It supports a rich library of multi-lingual voices and low-latency generation for fast workflows. See the list here.

Key Features

• Natural prosody with clear, humanlike articulation
• Multilingual support with strong English numeral/date reading
• Fine control via similarity and stability sliders
• Speaker Boost to enhance English number and unit delivery

Pricing

• $0.05 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 script in the text field.
2. Choose a voice_id (for example: Gigi, Callum, Alice; see the voice list for more).
3. Optional controls • similarity: 0–1 (higher = closer to the base voice timbre) • stability: 0–1 (higher = more consistent delivery) • use_speaker_boost: improves English number and unit reading
4. Run to synthesize and preview your audio.

Notes

• For best prosody, keep sentences clear and use punctuation; split very long text into smaller chunks.
• Ensure the voice_id is valid; use the official list linked above.
• Speaker Boost is especially helpful for finance, time, and measurement scripts.
