Key Features

Speech-to-Text
SpeechGen is an online AI voice generator with 5,000+ realistic voices. Built on advanced neural synthesis infrastructure, this text to voice AI handles anything — from a single sentence to an entire book.
Languages and formats
Available in 150 languages, with downloads in MP3, WAV, and FLAC. Pay as you go — buy Credits when you need them, use them at your own pace. Start free: 1,000 characters with no account required.
Document to audio
Upload any document — SpeechGen extracts text and converts it to audio.
Audio transcription
Upload any audio file — accurate text back.
Video transcription
Extract speech from video files directly.
Synced subtitle audio
Upload a subtitle file — each line is voiced at its exact timecode. Drop the audio straight into your video editor, already synced.
Smart Cache
Fix a typo, proof out loud, tweak a word. SpeechGen tracks your last synthesis — regenerate identical content and nothing gets deducted.
Chapter splitting
Type <cut> on its own line — each segment exports as a separate audio file. No audio editor, no manual splitting.
Music library
Pick from the built-in AI music library or upload your own. Mix voice and background music at the right levels — without leaving SpeechGen.
Multiple speakers
Assign different voices to different paragraphs using <Name> tags. Interviews, characters, training scripts — one export.
SSML controls
Insert SSML tags directly in your text: pause for exactly 1 second with <break time="1s"/>, or add a sound effect with <sound id="4807" name="assistant"/>.
Voice preview
Dial in voice, speed, and pitch — preview any combination with your own text before converting. No characters deducted on samples.
