What SpeakEasy has that Lemonfox doesn't
SRT & VTT Subtitles
Pass response_format=srt or vttand get a subtitle file back directly. Lemonfox returns JSON only — you'd have to build your own SRT formatter.
Audio Translation
Set translate=true to transcribe any audio and output English text in a single API call. Lemonfox requires a separate task parameter with limited support.
TTS Word Timestamps
Set word_timestamps=true in the TTS API to get per-word timing alongside the audio. Perfect for karaoke-style highlighting or lip-sync animation.
Generate subtitles directly from audio
SpeakEasy is the only affordable speech API that returns SRT and VTT files natively.
