SpeechGen

SpeechGen is a browser-based text to speech service built around credits rather than a monthly subscription. You paste text, choose a voice and quality tier, and download audio in formats such as MP3, WAV, FLAC, OGG, or OPUS. Beyond narration, the same workspace can turn subtitles into timed audio, add background music, run multi-speaker dialogue, and transcribe audio or video files back into text.

Key Features

• More than 5,000 voices across 150 languages and regional accents, grouped into Standard, Pro, and HD quality tiers.
• A text editor with SSML support, speed, pitch, and volume controls, and a dialog mode for multiple speakers in one file.
• Smart Cache that regenerates identical text without charging credits again.
• Uploads of PDF, DOCX, or SRT files, with long projects of up to two million characters per generation.
• Subtitle to audio conversion that voices each SRT or VTT line at its exact timecode.
• Built-in background music and sound library for mixing under narration.
• Audio to text and video to text transcription with speaker labels and language support.

Who is it for

• Video creators who need voiceovers for YouTube, TikTok, or Reels.
• E-learning and training teams producing narrated lessons at scale.
• Localization teams creating audio guides and campaigns in several languages.
• Small businesses building phone menus, announcements, or audio guides.
• Podcasters and animators who want multi-voice dialogue and music in one place.

What can you do with SpeechGen

• Convert a script into narration and download it as MP3, WAV, FLAC, OGG, or OPUS.
• Assign different voices to speakers and merge the result into a single file.
• Upload a subtitle file and generate audio that is already synced to the video.
• Add music from the built-in library and mix it with the voice track.

• Automate generation through the REST API or integrate text reading into an app.

How does SpeechGen work

1. Open the editor in a browser and paste or type your text, or upload a PDF, DOCX, or SRT file.
2. Pick a voice and language, then choose a Standard, Pro, or HD tier depending on quality needs.
3. Adjust speed, pitch, volume, and pauses, or split lines between speakers in dialog mode.
4. Convert the text and review the generated audio in the browser.
5. Download the file in the format and bitrate you need; repeated identical text is cached for free.

FAQ

Is there a subscription?

No. SpeechGen uses pay-as-you-go credit packs, and credits stay valid for one year from purchase or the latest top-up.

Can I use the audio commercially?

Yes. A commercial license is included with every pack, and files are delivered without watermarks.

Which languages are supported?

The platform lists more than 150 languages and accents, with regional variants for many of them.

What is Smart Cache?

Smart Cache tracks your last synthesis, so regenerating identical text does not cost credits, which is useful when fixing a typo or proofing a script.

Can I create multi-speaker audio?

Yes. Dialog mode lets you assign a different voice to each speaker and merge them into one file, which suits interviews, audiobooks, and explainers.
