  4. Clone a specific voice or accent from approved samples
  5. Offer a range of voices, accents and tones
  6. Adjust emotional tone of the generated speech
  7. Generate speech in multiple languages
  8. Expose an API for integration into other software
  9. Provide SDKs and adapters for easier integration
  10. Support on-premise deployment on customer infrastructure
  11. Handle managed compute so buyers do not manage GPUs
  12. Adjust speed, pitch and emphasis parameters
  13. Play real-time preview before finalizing
  14. Normalize numbers, addresses and formatted text correctly
  15. Return word-level timestamps for each word
  16. Support SSML markup for pronunciation and pacing
  17. Keep the model open source and customizable
  18. Provide a user-friendly interface for managing speech generation
  19. Compare the reviewed result with the recorded baseline and value assumptions
  20. Capture corrections and named-owner approval before consequential use
  21. Export a versioned reviewed speech configuration and generated audio with source references and unresolved questions

Questions

Do I need to know how to code?

No. You copy and paste the prompts on this page into ChatGPT or Claude, and the AI does the building. When it asks you something, you answer in your own words.

What does it cost?

The quick version, the app pack and the step-by-step instructions are for members: you pay the membership price, not a price per app (see the plans). Building the full app uses your own ChatGPT or Claude subscription. Putting it online is often cheap or no cost at the start, and your AI tells you before anything costs money.

How long does it take?

The quick version: about two minutes. The real app: an afternoon for a first version you can use, longer if you want every feature.

Can I change it to fit my business?

Yes. Tell your AI what to change in plain words, like “add a column for the price” or “use our logo and colours”. Or have Nexibeo build and customise it for you.

More detailsHow the AI works, safeguards and what to build first

Reduce the number of rented speech subscriptions while keeping one owned pipeline for real-time spoken audio. For product and platform teams adding natural-sounding spoken audio to their own applications, convert approved scripts, voice samples, language settings and latency targets into reviewed speech configurations and generated audio linked to their integration. The benefit is a testable hypothesis, measured through accepted audio minutes per delivery hour and corrections after integration; do not assume that AI output alone produces business value.

Confirm the buyer's problem and scope, collect approved scripts, voice samples, language settings and latency targets, then follow this sequence: 1. Convert written text into spoken audio. 2. Generate audio with low latency for immediate responses. 3. Stream text in and audio out as it is produced. Resolve uncertain cases with qualified reviewers, approve reviewed speech configurations and generated audio linked to their integration, and measure accepted audio minutes per delivery hour and corrections after integration against a documented baseline.

How the AI works

Use AI to interpret permitted inputs, suggest structured mappings and generate candidate outputs for the three stated task modules. Use deterministic code for arithmetic, schema validation, hard constraints and reproducible tests. Review source-linked explanations and uncertainty before accepting results. One fixed language set and approved voice library; final voice consent and content checks remain editorial. A model suggestion is never a verified fact, professional decision or authorization to act.

Safeguards

Preserve speaker consent, source attribution, pronunciation accuracy and usage permissions. Speakers approve voice cloning and publication scope. One fixed language set and approved voice library; final voice consent and content checks remain editorial. Keep all consequential actions under authorized human control and do not fabricate missing inputs, permissions, professional judgments or market evidence.

What to build first

Pilot scope: One fixed language set and approved voice library; final voice consent and content checks remain editorial. Implement one approved input format, a bounded representative case set and the first two task modules: convert written text into spoken audio; generate audio with low latency for immediate responses. Support the third module with operator review: stream text in and audio out as it is produced. Include source references, corrections, basic organization access, approval states, export and value measurement. Use managed operator assistance for unresolved exceptions. The cost estimate covers this narrow prototype, not unrestricted multi-tenant scale, complex production integrations, specialist certification or physical operations.

What it can connect to

Customer-owned scripts, authorized voice samples and permitted research sources. Cloud audio storage, application import/export and delivery destinations. Start with file exchange and validate destination specifications before promising direct publishing. Start with authorized file exchange. Validate current provider access, usage rights and schema behavior before promising a connector.

The screens in detail

Primary screens: Voice and script setup, Editable generation preview, Integration and delivery. Use a thumbnail gallery for projects, a large central editing canvas, and a right-hand panel for voices, parameters and comments. Let users compare versions side by side. Display draft, changes requested and approved states. Provide a client preview link with comments anchored to the relevant audio segment. Make the task-specific outcome reviewed speech configurations and generated audio linked to their integration visible beside its evidence, review state and value baseline.
