Overview

Audio Pronunciation Compare analyzes a reference recording and a learner recording to compare rhythm, pitch contour, timing, and a rough speech-spectrum proxy. It provides explainable acoustic similarity results without recognizing words or phonemes.

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

1Upload one reference audio file and one learner audio file.
2The tool extracts normalized acoustic feature sequences from both recordings.
3It aligns the sequences for comparison across timing, rhythm, pitch contour, and speech-band spectrum.
4The 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.

Examples

1. Compare a language learner’s sentence recording

Language learner

Background

A learner records the same sentence as a reference speaker and wants to review differences in rhythm and pitch movement.

Problem

The learner needs an acoustic comparison without relying on word transcription or phoneme recognition.

How to use

Upload the reference speaker’s recording as Reference Audio and the learner’s recording as Learner Audio.

Outcome

The tool returns aligned comparison information for timing, pitch contour, rhythm, and the rough speech-spectrum proxy.

2. Review practice recordings for intonation

Language teacher

Background

A teacher has a model recording and a student recording for the same speaking exercise.

Problem

The teacher wants a structured view of broad acoustic differences before giving pronunciation practice feedback.

How to use

Upload the model recording as Reference Audio and the student recording as Learner Audio.

Outcome

The JSON result provides explainable similarity information across pitch contour, timing, rhythm, and speech-band spectrum.
