What is Koro about:
TEXT TO SPEECH:

- Mix and match voices: choose from built-in voices or blend them together to create your own unique sound. Make it sound just right for you.
- Text import: drop in text files or PDFs and Koro will read them out loud. Great for articles, documents, or anything you want to listen to.
- Share your audio: save speeches as audio files and share them anywhere. Listen back anytime, even without the app.
- Advanced Customization: if some words don’t sound right, add their pronunciation at phoneme level for a perfect speech.
TRANSCRIPTION (English):
- Live transcription with Whisper.
- Extract speech from video and audio files.
SUMMARIZATION:
- Summarize text with a local language model.
