AI Voiceover Generator for Documentaries | Text And Speech

Text And Speech allows granular control over voice modulation, including pitch adjustments (-50% to +50%), speech speed (50% slower/faster), and strategic pauses (250ms–1.25s). Documentaries about environmental crises might use a somber, slow-paced tone, while historical retrospectives could benefit from a formal, measured delivery. The Intonation Modulation tool lets creators emphasize keywords like species names in wildlife films or dates in historical docs. Integrate custom pronunciations for technical terms (e.g., scientific nomenclature) via IPA or phonetic guides.

Supporting 20+ languages—including British English, Brazilian Portuguese, and Mandarin—Text And Speech ensures regional authenticity. A documentary about the Amazon Rainforest could feature Brazilian Portuguese narration with indigenous vocabulary, while a European history series might opt for Received Pronunciation. The Accent Localization feature adjusts idioms and cultural references, avoiding literal translations.

Drag-and-drop video, image, or audio files into the editor to align voiceovers frame-by-frame. Adjust audio timelines to match slow-motion wildlife shots or rapid-cut interviews. The Auto-Sync feature analyzes scene changes and suggests pause points. For example, a war documentary might sync artillery sound effects with voiceover lines about historical battles.

Invite editors, translators, and directors to comment on specific voiceover segments. Track changes with Version History and revert to previous drafts. Role-based access ensures translators only edit language tracks, not pacing. Teams working on a climate-change documentary can simultaneously adjust German and French voiceovers while the lead producer monitors consistency.

Text And Speech offers SOC 2 compliance, end-to-end encryption, and geo-restricted access for projects involving classified data. Government agencies producing documentaries on cybersecurity can restrict voiceover access to vetted staff. The Audit Log tracks every edit, while auto-redaction blurs sensitive terms in exported files.
