Lemonfox Text-to-Speech API review
A $5 monthly API for compatible, format-flexible text-to-speech workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Lemonfox Text-to-Speech API converts text into audio through OpenAI- and ElevenLabs-compatible APIs. It is aimed at developers building voice assistants, blog narration, video voice-overs and other programmatic speech-generation workflows. The product supports multiple voices and accents, language selection across eight languages, real-time streaming, adjustable speech speed and word-level timestamps. It is available through the web and API, with downloadable audio responses in MP3, Opus, AAC, FLAC, PCM, OGG and WAV formats.
Pricing is straightforward: the API plan costs $5 per month and includes 10 million credits. The published plan describes those credits as covering 30 hours of speech-to-text or 2 million characters of text-to-speech. There is no free plan. For buyers comparing entry-level API options, the low monthly price and compatibility with two established API formats may reduce the need to redesign an existing integration. The plan structure remains narrow, with one listed paid tier rather than a choice of feature-based packages.
The strongest fit is for teams that need programmatic speech generation with streaming, voice and accent options, speed control, timestamps and several export formats. Compatibility with OpenAI and ElevenLabs can also suit applications designed around those API patterns. Buyers seeking a broader integration ecosystem, verified voice cloning or a free starting tier should look elsewhere. Lemonfox is best considered a focused, low-cost TTS API for developers who value compatibility and output flexibility over a wider platform offering.
