I built the backend processing and API response flow

AUDIO TO TEXT

A speech-to-text pipeline that accepts audio, handles backend processing, calls transcription APIs, and returns cleaned text output.

01

Project Overview

Audio to Text is a prototype transcription utility that converts audio input into text using an AI transcription API. It is for anyone who needs quick transcription for notes, clips, study material, or automation workflows.

02

Problem / Motivation

Audio content is useful, but it is painful to search, skim, or reuse without text. Manual transcription wastes time, and many quick tools hide the actual backend flow. I wanted to build the pipeline myself so the moving parts were clear.

03

Architecture / System Design

The backend flow is built with Python and Flask. It accepts an audio upload, validates the request, prepares the payload for the transcription provider, receives the model output, then normalizes the response before returning it to the frontend.

The system is designed as a direct utility first. Once the transcription is reliable, it can be extended into summaries, searchable transcripts, or automated note generation. Pehle text sahi nikalo, then fancy features.

04

Key Features

The tool keeps the workflow focused on reliable transcription.

  • Audio upload and backend request handling.
  • AI transcription API integration.
  • Structured response cleanup before display.
  • Prototype-ready flow for future summaries or transcript search.
  • Simple utility design for practical use.

05

Technical Challenges

Audio workflows can fail in many small ways: unsupported formats, large files, slow responses, provider errors, and messy output formatting. The main challenge was keeping the pipeline predictable instead of assuming every upload behaves nicely.

06

Solutions / Engineering Decisions

I kept the backend as the control point for validation and provider interaction. That gives room to add file constraints, retries, and better response formatting later without pushing fragile logic into the client.

07

Outcome / Final State

The prototype establishes a working speech-to-text flow with a clear backend boundary. It is ready to grow into a more complete transcription and study utility once storage, history, and post-processing are added.
