VoiceStudio

VoiceStudio is a local voice-production app for creators and developers who need tools beyond speech generation. Its strongest case is the range of work it brings together; the trade-offs are local hardware demands and separate licences for speech models.

Overview

The open-source desktop app supports voice cloning, voice design, dubbing, dictation, transcription, and audiobook creation. Its local-first approach suits people who want voice data on storage they control, but it is not a substitute for the hosted cloud service: the public build has neither the hosted dashboard nor the Cloud API.

The maker says recordings, generated audio, transcripts, and derived voice data are not sent to its website or control plane. The app can still connect for updates and model downloads, or use a remote service when a network-backed adapter is explicitly configured. VoiceStudio was designed and built by Palash.dev; the maker identifies Palash Debnath, based in Agartala, India.

Key features

Voice creation and cloning

Voice design uses a written description rather than reference audio, letting users specify gender, age, accent, pitch, and emotion. Instant voice cloning and pronunciation controls add useful flexibility when creating speech for scripts or other production work. The important caveat is that VoiceStudio's AGPL-3.0 licence does not settle the licensing of the speech models: each has its own terms, and some may be research-only.

Dubbing, transcription, and audiobooks

The dubbing workflow transcribes and translates video, then re-voices it while keeping speakers separate and aligning timing to the original. That combination is useful for creators handling localized video, though the public build's local requirements may make it a poor fit for users seeking a hosted workflow. The app also supports dictation and transcription, multi-voice audio from scripts, and chaptered audiobooks from long text or EPUB files.

API and exports

The desktop app exposes an OpenAI-compatible local API at http://localhost:3900/v1, with speech, voices, transcription, and dubbing endpoints. The maker lists 26 engine adapters, including local text-to-speech and transcription engines and a configured-remote OpenAI-compatible ASR adapter. Exports include MP3, Opus, AAC, FLAC, WAV, and PCM. Developers can connect local workflows through the API, but it is not the Cloud API.

Pricing

The Open Source plan is free under AGPL-3.0, with no seat count or evaluation period; speech-model licences remain separate. This is the natural starting point for individual users comfortable managing local models and their terms. VoiceStudio says commercial use is permitted under AGPL-3.0, but that does not override a model's own licence.

Pro costs $99 a year, billed $99 per user / year, and includes 1 user, 3 active devices, and 3 concurrent uses. It fits one user who needs those usage allowances. Lifetime costs $299, paid once, billed $299 per user one-time, with the same 1-user, 3-device, and 3-concurrent-use limits. It may suit a buyer preferring a one-time payment, but does not add seats or concurrency over Pro.

Enterprise has custom pricing and flexible terms for larger teams. An enquiry is not a purchase, quote, agreement, or licence grant. There is no free trial. Cloud is in early access and invites users to request access for free usage credits, but that does not make the hosted dashboard or Cloud API part of the public build.

Platforms

VoiceStudio supports Linux, macOS, and Windows, as well as web, API, and self-hosted platforms. The download FAQ estimates about 8 GB of RAM and around 10 GB of disk for models, recommends 16 GB or more of RAM, and says a GPU is optional; CPU use is slower. That makes local use more appealing for users with suitable hardware than for those seeking a lightweight, hosted option.

Who it's for

VoiceStudio is best for creators who combine several voice tasks, and developers who want a local API alongside the desktop app. It is a strong fit when local control and broad workflows matter more than a managed cloud interface. Those who need the hosted dashboard, Cloud API, or a lower-hardware path should look elsewhere; commercial users should also check the licence of every model they use.

Pros and cons

Pros

• Broad voice workflow: cloning, dubbing, transcription, dictation, and audiobook creation share one app.
• Local control: the maker says recordings and derived voice data stay on user-controlled storage rather than going to its website or control plane.
• Useful integration options: the local OpenAI-compatible API and six export formats give developers and creators ways to connect or move audio.

Cons

• Hardware matters: the FAQ recommends 16 GB or more of RAM, and CPU use is slower.
• Model terms vary: some speech models may be research-only, despite the app's commercial-use permission.
• Cloud is not in the public build: users seeking a hosted dashboard or Cloud API will not get them there.

Alternatives

For a different balance of hosted plans and platform options, Fish Audio has a free tier with 8,000 monthly credits, up to 7 minutes of generation, up to 500 characters per generation, and 3 public voice slots.

Voicebox is another free-plan option, with Android and iOS support in addition to desktop, API, and self-hosted platforms.

Fish Speech is worth considering for its free tier of 8,000 monthly credits, up to 7 minutes per generation, and 3 public voice slots, with API, Linux, self-hosted, and web platforms.

Kits AI may fit users seeking a web or Windows option with a free plan that includes 15 conversion minutes, voice designer/blender, and Kits generative vocals, but no voice slots or download minutes.

Qwen3-TTS suits readers looking for free open-source models under Apache-2.0, with 0.6B and 1.7B models and 10 languages.

Chatterbox TTS offers free open-source models under MIT for research and development, on Linux, macOS, and self-hosted platforms.

CosyVoice is a free Apache-2.0-licensed repository with downloadable source code and models for users prepared to manage their own setup.

Sprag is a paid option for users considering per-hour speech-generation pricing.

For a broader shortlist, compare Voice Cloning Software, AI Voice Cloning Software, Text-to-Speech Software, and Voice Changer Software.

Verdict

Choose VoiceStudio if you want a local studio that spans cloning, dubbing, transcription, and long-form audio, with an API for connecting other software. Its main advantages are workflow breadth and local data control. Look elsewhere if you need the hosted cloud experience, lighter hardware requirements, or model licensing without separate checks.
