SpeechGen
SpeechGen.io is an online text-to-speech studio with more than 5,000 neural voices across 150 languages. Paste or upload text, pick a voice, tune speed, pitch, volume, and SSML tags, then export MP3, WAV, or FLAC files without a monthly subscription.
The editor supports long-form jobs, subtitle-to-audio conversion, document imports, and a voice cloning flow that builds a custom voice from a short audio sample. SpeechGen also runs audio-to-text transcription for uploaded files, videos, and YouTube links with SRT and VTT export.
New accounts receive free credits to test synthesis, and additional usage is sold as one-time credit packs through card or PayPal checkout. An API is available for developers who want to automate generation inside their own workflows.

Is SpeechGen subscription-based?
No. SpeechGen uses pay-as-you-go credits. You buy a credit pack when you need more synthesis or transcription minutes, and unused credits stay on your account.
What audio formats can SpeechGen export?
Generated speech can be downloaded as MP3, WAV, or FLAC. The editor also supports SSML markup for fine control over pauses, emphasis, pronunciation, and prosody.
Does SpeechGen support voice cloning?
Yes. Upload or record a short clean sample, confirm usage rights, and SpeechGen creates a custom cloned voice you can use in the main text-to-speech editor.
Can SpeechGen transcribe audio or video?
Yes. The Audio to Text dashboard accepts uploaded audio and video files or YouTube links, then returns transcripts with subtitle exports such as SRT and VTT.
