FAQ
What types of audio formats are supported?
MP3, WAV, and FLAC formats are supported. MP3 is automatically converted for processing.
Can I host the app online?
Yes, I’ll help you deploy it to platforms like Render, Vercel (frontend), or Heroku (backend).
Does the app work offline or online only?
The app runs online but processes everything server-side. Sphinx is an offline engine, so no third-party API is required.
Can you customize it for specific use cases like interviews or podcasts?
Absolutely! I can tailor the app for any specific workflow or niche.
Will I get the full source code with the delivery?
Yes, you will receive complete source code for both frontend and backend. It's well-structured and easy to understand.
Can the transcription text be exported in other formats like PDF or DOCX?
By default, the app provides .txt export. However, I can add PDF or DOCX export as a custom feature—just let me know!
Is there a file size limit for audio uploads?
The default limit is ~10MB, but I can adjust this based on your hosting platform and project needs.
Can I integrate this with a database to store transcriptions?
Yes! I can connect the app to a database (e.g., SQLite, PostgreSQL) to save and manage transcription history.
What if CMU Sphinx doesn’t give accurate results?
I can switch to a more accurate engine like Whisper (OpenAI) or Google Speech-to-Text upon request (may require API keys).
