Tool Information

Lemonfox provides low-cost speech-to-text and text-to-speech APIs, including multilingual transcription, translation, diarization, and voice generation. Developers should secure API keys, obtain recording consent, validate transcripts, and authorize any synthetic voice use.

Users begin with a limited test, provide only authorized and necessary inputs, configure privacy and output settings, compare results with the original source or a trusted benchmark, correct errors, and keep a responsible person in control before publishing, sharing, or automating consequential work.

A one-month free trial is available. The base plan costs $5 per month for 10 million credits, roughly 30 transcription hours or two million TTS characters, with additional million-credit blocks from $0.50.

AI output can be inaccurate, biased, incomplete, stale, or misleading and the service may process confidential or personal data. Protect credentials, review retention and model-training terms, respect copyright and consent, monitor costs and permissions, and add specialist review for regulated or high-impact uses.

Pros and Cons

Pros

  • Lemonfox provides a straightforward speech-to-text API
  • The listed base price is $5 per month
  • The base allowance covers about thirty hours of transcription
  • Additional credits are priced transparently
  • A one-month free trial supports integration testing
  • More than one hundred languages are supported
  • The API can translate speech during processing
  • Speaker diarization labels different voices
  • Whisper large-v3 provides a capable recognition foundation
  • Audio can be uploaded as a file object
  • A public media URL can be supplied instead of uploading directly
  • Common audio and video container formats are accepted
  • JSON; plain text; SRT; VTT; and verbose JSON outputs suit different workflows
  • Timestamps in verbose output support navigation and editing
  • The same credit pool can be used for text-to-speech
  • The site says processed data is deleted immediately and EU processing is available

Cons

  • The service targets developers rather than offering a full editing application
  • Local file uploads are limited to 100 MB
  • URL-based files are capped at 1 GB
  • Speaker diarization currently supports at most four speakers
  • Whisper can mishear names; accents; codes; numbers; and specialist terminology
  • Speaker labels can swap when voices overlap or sound similar
  • Translation adds another layer where meaning and terminology can change
  • Immediate-deletion claims should be confirmed in contractual data-processing terms
  • Providing a public URL can expose media beyond the intended API workflow
  • EU processing availability may require configuration or a specific agreement
  • A low price does not guarantee latency or uptime under production load
  • Credits combine different APIs; making usage forecasting less intuitive
  • Subtitle timing still needs human adjustment for readable line length and pace
  • Transcribing meetings; calls; or interviews requires consent and lawful handling
  • Sensitive recordings need encryption; minimal retention; access controls; and deletion logs
  • Critical transcripts should be reviewed against the original audio before use
