A starting point.
Prepare an alternate narration with Eleven v4 Turbo. For a comparison with v4, reuse the same script, voice and delivery cues.
Before you publish.
Compare the complete audio for pronunciation and expression. Record actual turnaround and quotes rather than assuming an advantage from the Turbo name.
Review the quote before running. A failed generation releases its reserved credits. Download the results you want to keep; stored media is retained for 30 days.
Settings and model questionsCheck the available settings and guidance when preparing your input.
Inputs and settings
Send text, choose voice and record stability and similarity_boost. Keep normalization and language settings consistent across comparisons.
Choose output_format for the destination. A seed requests best-effort repeatability; it does not guarantee identical audio.

Use Eleven v4 Turbo through the API.
Start with this model ID for the endpoint featured on this page:
elevenlabs/tts/eleven-v4-turbo
Input requirements belong to this model ID. Check a different mode’s schema separately when switching modes.
Check the current model schema for supported inputs and options. Other tasks may use different model IDs.
From quote to result.
Request a credit quote for your input and settings before submitting a generation. A sample output or the price of another model is not a quote for your request.
Follow the generation workflow, then poll the job for its status and result. The API and studio use the same balance.
