## Overview

Aligns normalized acoustic feature sequences and reports explainable timing, pitch-contour, and speech-band spectrum similarity. It does not recognize words or phonemes and must not be used to grade accents or diagnose speech.

## Inputs

- **Reference Audio** (file)
- **Learner Audio** (file)

## When to use

- Compare a learner’s timing and rhythm with a reference recording.
- Review pitch-contour differences during language practice.
- Inspect broad acoustic similarity between two speech recordings without transcribing them.

## How it works

- Upload one reference audio file and one learner audio file.
- The tool extracts normalized acoustic feature sequences from both recordings.
- It aligns the sequences for comparison across timing, rhythm, pitch contour, and speech-band spectrum.
- The result is returned as JSON with explainable similarity information.

## Use cases

- Language learners comparing their rhythm and pitch with a reference speaker.
- Teachers reviewing broad timing and intonation differences in practice recordings.
- Speech and audio researchers inspecting aligned acoustic feature similarity without word recognition.

## Frequently asked questions

### What files can I upload?
