What is SpeechGen?
SpeechGen is a natural text to speech tool. Browser based neural text to speech with 5,000+ voices in 150 languages, SSML control, multi voice scripts, SRT syncing and a REST API. Pay as you go credits, no subscription.
SpeechGen is a browser based text to speech studio built on neural synthesis, with a catalog of more than 5,000 voices spread across 150 languages. Text is pasted into an editor, a voice is selected, and audio comes back as MP3, WAV, FLAC or several other formats. The homepage positions it for anyone producing narration at volume: marketing explainers, e-learning modules, phone and IVR prompts, museum audio guides, industrial safety announcements and localization projects. No software install is involved, and the first 1,000 characters can be generated without an account. The editor carries more production control than most competitors put on a single page. SSML tags can be typed inline to set pauses, pitch, rate, emphasis and phonemes, or inserted from a toolbar. Placing a name tag before a paragraph assigns a different voice to it, so a dialogue, interview or multi character script exports as one file. Typing a cut tag on its own line splits the script into separate audio files per segment, which is how the company describes turning a book into one file per chapter. A built in music library plus support for uploaded tracks lets voice and background sit at chosen levels without opening a DAW, and SRT or VTT uploads voice each subtitle line at its exact timecode. Adjacent tools round out the workflow: PDF and DOCX to audio conversion, audio transcription in 140 languages with speaker labels and timestamps, video transcription, and a REST API that returns an audio URL from a single HTTP call. Output quality is tiered as Standard, HD and PRO at 0.5, 1 and 2 credits per character respectively, and downloads are watermark free even on the free allowance. The commercial model is the real differentiator. Credits are purchased once and expire after 365 days rather than monthly, and a smart cache means regenerating unchanged text costs nothing, which suits teams that proof scripts out loud and revise line by line. That makes SpeechGen a closer match for intermittent, budget conscious production than for anyone who needs a fully managed dubbing pipeline, where dedicated video localization suites still do more.
How do you use SpeechGen?
1Paste your script into the editor
Open the homepage editor and type or paste text. Documents such as DOCX, PDF and SRT files can be uploaded instead, up to roughly 1,000,000 characters.2Pick a voice and shape the delivery
Browse the voice library and preview candidates with your own text before spending anything. Adjust speed, pitch and volume, and add SSML tags if you need precise pauses or emphasis.3Lay in background music and speakers
Choose a track from the built in music library or upload your own, set the mix level, and tag paragraphs with different voice names when the script needs more than one speaker.4Convert and download the audio
Press Convert to Speech and select the output format and bitrate. The file downloads when ready, watermark free, and is stored in your history for later reuse.5Register to unlock the free daily allowance
Creating a free account removes the watermarks, raises the allowance and extends the daily free characters to 3,000 for seven days. A card is not required at this step.6Buy credits for ongoing work
When the free allowance runs out, pick a credit pack starting at $4.99. Credits stay valid for 365 days and cover the commercial license, the API and every voice tier.
Pros and cons
Pros
- Credit packs last 365 days instead of expiring monthlyAI
- Smart cache makes regenerating identical text freeAI
- Multi voice scripting and cut tags handle dialogue and chapter splits in one exportAI

- Built in transcription, PDF and SRT tools reduce the need for other appsAI
Cons
- Pay as you go means the cost per character rises with volume, with no flat monthly capAI
- Quality tiers are priced separately, so HD and PRO work at 2 credits per character adds up on long narrationAI
- Support appears to lean on documentation and FAQ rather than stated live chat or phone channelsAI
- No native mobile or desktop app is described on the homepage, so all work happens in the browserAI
- Uploaded documents and subtitle syncing are handled inside the product, but no third party plugin ecosystem is documentedAI
