Everything you need for voice processing and transcription
Convert any text into natural-sounding speech using advanced ONNX models. Choose from multiple languages and voices, adjust speed, and generate high-quality MP3 audio files instantly.

Simple and powerful REST API for seamless integration into your applications. Generate API keys, authenticate requests, and access all features programmatically. Use the same endpoints from Cursor via our MCP server (webvoice-mcp).
Pay-as-you-go credit system with transparent pricing. Get free monthly credits, purchase credits as needed, or subscribe for recurring credits. Credits are consumed based on audio duration processed.
Translate transcribed text using advanced AI models. Perfect for multilingual workflows. Integrate translation seamlessly after transcription for complete language processing.
Track all your TTS generations and transcriptions. View detailed history, download previously generated files, monitor credit usage, and analyze your usage patterns with comprehensive analytics.
Create images from text prompts using MiniMax image models (e.g. image-01), with aspect ratios for social or slides. Use the REST API or admin tools; credits apply per successful generation.
Pick different LLMs per thread — fast Groq hosts, Moonshot Kimi, MiniMax, and other curated providers. Compare answers, tune costs with per-request credits, and combine chat with voice workflows.
