Voicebox vs Voicemaker

Voicebox is a free, open-source local AI voice studio for voice cloning, speech generation, dictation, and agent voice output. Its desktop app can clone a voice from as little as three seconds of audio, supplied by file, microphone recording, or system capture. The maker lists seven text-to-speech engines for cloning, preset voices, and delivery control. A timeline editor supports multi-voice narratives, arranging tracks, trimming clips, and mixing conversations; effects include pitch shift, reverb, delay, and compression. Dictation uses a global shortcut to send transcripts to the focused text field or clipboard, with local Whisper models supporting 99 languages. MCP-aware agents such as Claude Code, Cursor, and Cline can speak through Voicebox, and a local REST API provides speech generation and related functions. The privacy policy says the offline desktop app requires no account and does not send recordings, profiles, transcripts, generations, or settings to the maker. Local is free with unlimited local generations and captures. Cloud and mobile sync are marked as coming soon, and cloud pricing and limits are not final.

Voicemaker turns typed or pasted text into audio, with controls for voice speed, pitch, and volume. Its listed tools also include speech-to-speech voice conversion and speech-to-text. The voice library lists 500 voices, and the service supports up to 140 languages on paid plans; the Free plan lists 120. Output formats include MP3, OGG, WAV, OPUS, AAC, and telephony audio. Voicemaker is available on the web and through a pay-as-you-go REST API for integrating text-to-speech, speech-to-speech, and speech-to-text into apps and workflows. Plans use credits, charged at conversion rather than download, with CJK characters using two credits each. The Free plan costs nothing and allows limited generations, up to 250 characters per conversion, and personal use. Starter costs $5 a month and includes 200,000 monthly credits, a 3,000-character limit, and 140 languages. Paid plans include commercial usage rights; the free tier is for personal, internal evaluation, or non-commercial use. Voicemaker supports SSML.
