OpenAI TTS (Text to Speech)- Best for
- Simple narration with a predictable preset voice

- Why choose it
- Supports 646 languages plus voice attributes, pace, target duration, references, and nonverbal cues.
- Watch for

- Expressive multilingual narration and dialogue
- Why choose it
- Supports expressive audio tags, native two-speaker dialogue, and a broad language and voice set.
- Watch for
- The model accepts up to 4,000 characters per request; split longer scripts at semantic boundaries.
Kokoro 82M (English TTS)- Best for
- Efficient English text-to-speech
- Why choose it
- A compact English-focused model can be useful for quick previews and high-volume drafts.
- Watch for
- It is not the right choice for multilingual output or identity cloning.
What text-to-speech cannot guarantee
Names, acronyms, numbers, formulas, URLs, and mixed-language text may be spoken incorrectly unless the script is prepared and reviewed.
Emotion, pauses, emphasis, breath, and sentence rhythm depend on the model, voice, text, and supported controls.
Character limits and context vary. Split long narration at semantic boundaries and check continuity, loudness, and pace across segments.
Use references only with authorization and disclose synthetic speech when the audience could reasonably mistake it for a real person.
Final speech may require trimming, silence control, de-essing, normalization, captions, mastering, and a human language check.

Text-to-speech FAQ
Which languages are supported?
Language support varies by model. Select a model and use only the languages shown in its live contract.
Can I control emotion and speaking style?
Some models expose emotion, style, speed, or inline performance controls. Models without those fields do not promise them.
Can I clone a voice?
Only on models that support voice references, and only for a voice you own or have clear permission to use.
How do I improve pronunciation?
Select the correct language, expand abbreviations, write numbers the way they should be spoken, use punctuation for pauses, and generate a short pronunciation test before a long script.
How should I handle a long script?
Split it at chapters, scenes, or paragraphs within the selected model’s character limit. Preserve voice and settings, then check transitions, loudness, pace, and pronunciation across every segment.
Which audio format should I export?
Choose a lossless format for editing when available and a compressed format for delivery only after quality review. The live model contract lists available formats.
Can I use generated speech for accessibility?
It can support drafts and accessible alternatives, but important educational, safety, navigation, or public-service narration needs human review for accuracy, clarity, pace, and pronunciation.
Do I need to disclose that a voice is synthetic?
Disclosure requirements depend on context and law. Disclose whenever an audience could reasonably believe the audio is a real person or when a platform, contract, or policy requires it.
