Model selection guide

Choose a text-to-speech model by script and delivery

Language, preset voices, designed identity, cloning, latency, pronunciation, and performance controls differ by model.

OpenAI TTS (Text to Speech)

Best for: Simple narration with a predictable preset voice
Why choose it: Keeps the input contract compact for product voiceovers, guides, and straightforward spoken content.
Watch for: Preset speaker and style options are narrower than voice-design or cloning models.

OmniVoice

Best for: Massively multilingual speech, voice design, mixed language, and authorized cloning
Why choose it: Supports 646 languages plus voice attributes, pace, target duration, references, and nonverbal cues.
Watch for: Proofread pronunciation and identity in every target language.

xAI Text-to-Speech

Best for: Expressive preset text-to-speech
Why choose it: Provides a dedicated TTS contract for conversational or character-oriented delivery.
Watch for: Use only the voices, languages, and formats visible in the live settings.

Inworld TTS-1.5 Mini

Best for: Low-latency product and conversational speech
Why choose it: Useful where response speed matters and a dedicated compact TTS model fits the script.
Watch for: Fast generation does not remove the need for pronunciation and loudness review.

Gemini 3.1 Flash TTS

Best 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.

Known limits

What text-to-speech cannot guarantee

Pronunciation is not automatic truth

Names, acronyms, numbers, formulas, URLs, and mixed-language text may be spoken incorrectly unless the script is prepared and reviewed.

Natural delivery varies

Emotion, pauses, emphasis, breath, and sentence rhythm depend on the model, voice, text, and supported controls.

Long scripts need segmentation

Character limits and context vary. Split long narration at semantic boundaries and check continuity, loudness, and pace across segments.

Voice rights still apply

Use references only with authorization and disclose synthetic speech when the audience could reasonably mistake it for a real person.

Output needs production review

Final speech may require trimming, silence control, de-essing, normalization, captions, mastering, and a human language check.

Clear answers

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.
