There are dozens of text-to-speech providers, each with its own API, voice catalog, pricing model, and output format. AI TTS Microservice brings them all into one place — so you can focus on finding the right voice instead of managing integrations.

The Fragmentation Problem

If you've ever needed high-quality AI narration, you've probably hit the same wall: Google Cloud and Azure TTS has great multilingual coverage, Polly has familiar broadcast-style voices, Kokoro delivers expressive open-source quality, and Gemini TTS pushes the frontier on ultra-realistic speech. But trying them all means signing up for separate platforms, learning separate APIs, managing separate billing, and writing separate integration code for each one.

For a single project that might be tolerable. For ongoing production work — narration pipelines, content localization, accessibility audio, faceless video, podcasts, language learning — it becomes a serious drag on velocity.

AI TTS Microservice exists to eliminate that friction entirely.

One Catalog. Every Provider. 90+ Languages.

The voice gallery is the heart of the platform. It's free to browse — no account required — and it puts every voice from every connected provider into a single searchable, filterable interface.

You can filter by provider, language, gender, voice family, and quality tier. Pin voices to a shortlist and preview them back-to-back with your own text. When you find the right one, you're a click away from generating full audio — no context switching, no separate dashboard.

Currently live in the catalog:

• Google Cloud TTS — Wavenet, Neural2, Chirp3-HD, and Studio voices across dozens of languages
• Gemini TTS — Google's latest ultra-realistic voices with expressive, conversational delivery
• Amazon Polly — Generative, Long Form and Neural voices with a broadcast-ready tone
• Kokoro — High-quality open-source TTS with natural prosody

Azure Speech, ElevenLabs, Cartesia, Deepgram, OpenAI, and others are on the roadmap. When they go live, they'll appear in the same catalog with the same workflow — no migration, no new integration.

Generation That Adapts to Your Workflow

Whether you need a five-second notification chime or a ten-hour audiobook, the generation flow handles it. Short clips render quickly; long-form scripts are processed in the background so you're never staring at a spinner.

You have full control over the output:

• Formats: WAV (lossless, ideal for production pipelines), MP3, or OGG/Opus
• Quality: Custom bitrate and sample rate for MP3 and OGG — dial in exactly what your pipeline needs
• Scale: Direct download or stream to disk with no size cap on exports

The platform adapts the available controls to each provider and voice automatically. If a voice supports speaking rate adjustment or SSML markup, those controls appear. If it doesn't, they stay out of the way. You never have to memorize which provider supports what.

Built for Every Use Case

The use cases are as wide as your imagination. Language learners practicing pronunciation and listening skills. Creators producing narration for documents, presentations, and e-learning content. Hobbyists experimenting with voices for personal projects. People with accessibility needs who depend on reliable, natural-sounding audio. Businesses generating short promotional voiceovers for products and services. The possibilities are genuinely endless — the only limit is what you can think of.

Sharing That Goes Beyond a Download Link

Most TTS tools end at the download button. AI TTS Microservice treats sharing as a first-class feature.

Every generation can be shared instantly:

• Public links — anyone can listen, no account needed
• Password protection — restrict access to private content
• Access codes — generate single-use or time-limited codes for teams, classrooms, or events, with bulk generation for larger groups
• Playlists — bundle multiple tracks into a single shareable link with drag-and-drop ordering
• QR codes — branded, downloadable QR codes for print materials, slides, or physical distribution

Recipients don't need an account to listen. Share links work in any browser.

A Library, Not a Downloads Folder

Every generation is saved to your library automatically. From there you can:

• Tag files with custom labels for quick retrieval
• Organize into collections by project, client, or campaign
• Bookmark voices and shared audio you want to revisit
• Track share history — see who accessed what and when
• Share collections as live links or point-in-time snapshots

The dashboard gives you a single view across all your generations, shares, storage usage, and activity history.

A Unified REST API for Developers

Everything available in the UI is also available through a REST API. One integration, one set of credentials, every provider in the catalog.

The developer experience is designed to get you from zero to audio in minutes:

• Simple auth: API keys created from your dashboard, prefixed with tts_
• Harmonized voice IDs: Every voice across every provider follows a consistent provider:voice-name format
• Async jobs with polling: Submit text, get a job ID, poll for completion — or use webhooks for real-time notifications
• Idempotency keys: Safe retries built in — no risk of duplicate charges on network hiccups
• OpenAPI spec: Downloadable spec for code generation in any language
• Interactive playground: Test requests directly in the docs before writing a line of code

Code samples are available in curl, Python, and Node.js. A complete quickstart takes about two minutes.

Enterprise-Ready from Day One

For teams and organizations with higher-volume needs, enterprise accounts unlock:

• Tiered usage rates (Starter, Growth, and Scale) with volume pricing
• 100 GB of long-retention storage
• Higher API rate limits
• Webhook delivery for real-time job notifications — integrate generation events directly into your pipeline
• Usage tracking and reporting

Pricing That Stays Out of the Way

Pricing is simple and usage-based — pay only when you generate. No contracts, no bundles. Subscribe to Pro for member rates and long-retention storage, or choose an Enterprise tier for volume pricing and higher limits. For enterprise customers, we offer tailored plans to match your scale and requirements.

There's a rates explorer and pricing calculator on the pricing page so you can estimate costs before generating a single character.

Private by Default

Your text and audio are yours. The platform follows segment-aware retention policies: pay-as-you-go users get short-lived storage to keep things lean; subscribers get long-retention with defined storage caps. You can delete stored audio anytime to free space.

What's Ahead

The provider catalog is expanding. Azure Speech, ElevenLabs, Cartesia, Deepgram, OpenAI, and additional open-source TTS engines are all on the roadmap. When they go live, they'll slot into the same catalog, the same API, and the same billing — no migration required.
