In their own words
Speechify
Speechify is a text-to-speech product available on Android, iOS, macOS, web, Windows, and through an API. Its listed capabilities include voice cloning, commercial use, and MP3 audio export, with support for 60 languages. The free plan costs nothing and includes 10 voices with a maximum speed of 1.5x. Premium costs $29 a month, billed monthly, and lists more than 1,000 voices, 60+ languages, and a maximum speed of 5x. Speechify was founded in 2017 and is headquartered in Miami, Florida, United States. The plans differ in voice count and maximum playback speed; Premium also specifies its language offering as 60+ languages. Buyers can weigh those limits against the listed platform access, language support, and MP3 export when choosing a plan.
Voicebox
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.
