What is SpeechGen?
SpeechGen is a browser-based AI text-to-speech service for turning typed or uploaded text into downloadable audio. Users choose among voices and languages, adjust delivery settings, and export a finished narration. The editor supports long scripts as well as short passages, with controls for speech timing, pronunciation, and mixing background audio. It also includes audio-to-text transcription, so the same credit balance can be used for speech generation or transcription.
What can SpeechGen do?
Speech and export controls
Adjust speed, pitch, volume, pauses, emphasis, and pronunciation. Download audio in formats including MP3, WAV, OGG, and FLAC.
Long-form and document input
Paste scripts up to 1,000,000 characters or upload DOCX, PDF, and SRT files. Text-based PDFs can be converted; scanned documents need OCR first.
Multispeaker and segmented output
Assign different voices to paragraphs using speaker tags, or insert <cut> on its own line to export separate audio segments.
Audio production tools
Add background music from the built-in library or upload a track, then mix it with narration in the editor.
Transcription and API access
Use credits for audio-to-text transcription, with speaker diarization, word-level timestamps, subtitle export, bulk export, and API access listed among included capabilities.
Use Cases
“Video and marketing narration”
Create voiceover audio for explainers, product launches, and other video scripts, with control over voice and pace.
“Courses and training materials”
Produce narrated lessons or language drills, including scripts that switch between speakers or languages.
“Phone systems and IVR”
Generate recorded business prompts and update them as service information changes.
“Books, papers, and reports”
Convert text-based PDFs or long scripts into audio for listening away from a screen; segmented output can separate chapters or sections.
“Localization and accessibility”
Create spoken versions in multiple languages and use transcription tools to generate timed subtitles from audio.
