VocalLab AI is an all-in-one AI voice production platform designed for creators, businesses, educators, developers, publishers, and marketing teams. It helps users transform written content into natural, expressive audio without the cost and complexity of traditional voice recording.
The platform combines realistic text-to-speech, instant voice cloning, Voice Design, audiobook production, video dubbing, speech-to-text, subtitles, and developer integrations in one workspace.
VocalLab AI offers three speech-generation models—Lite, Pro, and Studio—so users can choose the right balance of speed, quality, and creative control. Studio provides advanced control over pacing, emotion, pronunciation, pauses, and delivery through natural-language instructions and delivery tags.
Key features include:
• AI Voice Generation
Turn scripts, articles, advertisements, training materials, podcasts, and other written content into natural-sounding speech. Users can select from a growing library of professional voices and generate audio in MP3 or WAV format.
• Instant Voice Cloning
Create a voice clone from approximately 5–30 seconds of clean recorded audio. A recording of around 20–30 seconds generally produces the best results. Users must own the voice or have explicit authorization from the voice owner.
• Voice Design
Create an original voice using a written description rather than an existing recording. Users can describe the desired age, gender, accent, tone, personality, speaking style, energy, and intended use. VocalLab generates voice candidates based on that description.
Voice Cloning and Voice Design provide access to hundreds of language options and more than 130 accent variations, making it possible to create voices for localized and international content.
• AI Video Dubbing
Upload a video or audio file and automatically transcribe, translate, and dub it into another language. VocalLab separates the content into individual lines, preserves the original timing, and shows whether each translated line fits its available speaking window.
Users can edit translations, select different voices, keep the original audio for specific lines, create multiple takes, trim timing, and regenerate only the sections that need adjustment. Video dubbing is available in 15 major languages, while automatic transcription supports 30 languages.
• AI Audiobook Creation
Upload an entire EPUB, PDF, DOCX, or TXT manuscript up to 25 MB. VocalLab automatically detects chapters and characters, divides the content into manageable sections, and prepares voice casting.
Users can assign different voices to the narrator and characters, review the text, generate the audiobook chapter by chapter, and export the finished project as one combined MP3 file. This removes the need to copy and paste every line manually.
• Speech-to-Text
Convert recorded audio into editable text in 30 supported languages. This is useful for transcription, content repurposing, accessibility, subtitles, and preparing material for dubbing or voice generation.
• Captions and Timestamps
Generate subtitle and caption files in SRT format for videos, podcasts, courses, and other audio content. Caption generation is available through the VocalLab application, API, and MCP integration.
• API and MCP Integration
Developers and AI users can connect VocalLab to applications, automation platforms, and MCP-compatible AI assistants. Supported workflows include text-to-speech generation, voice cloning, Voice Design, and caption creation.
The hosted MCP server allows users to access VocalLab voice tools directly from supported AI environments. This makes it possible to create audio through conversational AI workflows without manually switching between multiple applications.
• Advanced Studio Controls
VocalLab Studio gives creators more control over how every line is performed. Users can guide emotion, pacing, emphasis, pronunciation, and vocal delivery. Delivery tags can add natural elements such as laughter, sighs, and breathing, while pause tags provide precise control over timing.
• Multilingual Content Production
VocalLab supports major languages including English, Spanish, French, German, Italian, Portuguese, Dutch, Polish, Russian, Arabic, Hebrew, Hindi, Japanese, Korean, and Chinese. Additional languages and regional accents are available experimentally, although quality may vary depending on the selected voice, language, and model.
VocalLab AI is suitable for:
• YouTube videos and social media content
• Advertisements and product demonstrations
• Podcasts and audio articles
• Audiobooks and narrated stories
• Online courses and educational materials
• Corporate training and presentations
• Video translation and localization

Paid plans include commercial usage rights for generated audio created with eligible professional voices. Users are responsible for ensuring that they own or are authorized to use the scripts, recordings, and voices included in their projects.
A free account is available with 60 points, approximately one minute of generation, one voice clone, and one Voice Design project. No credit card is required, allowing users to test the platform and compare different voices before selecting a paid plan.
VocalLab AI brings voice generation, cloning, localization, audiobook creation, and developer automation together in one platform. Its goal is to make professional voice production faster, more accessible, and easier to scale while still giving creators detailed control over how their content sounds.
