How SpeakTune Scores Your Recording

SpeakTune is built around a simple idea: if you can hear the difference, see the difference, and try one clear correction, your English speaking practice becomes much more useful.

The app currently focuses on three signals: Pitch Contour, Sentence Ending, and Voice Tension. Your feedback is designed to point you toward the one thing that will help most on the next attempt.

Overall score

The overall score is a quick progress marker. It is not a judgment of your English ability, your fluency, or your intelligence. It is a snapshot of how close this attempt was to the reference pattern for that sentence.

Use the number to notice trends. If your score rises over several attempts, the practice is working. If it stays flat, stop repeating blindly and focus on the weakest metric.

Pitch Contour

Pitch Contour measures how closely the rise-and-fall melody of your sentence matches the reference. SpeakTune compares the shape of the pitch pattern, not whether your voice is naturally high or low.

This matters for Mandarin and Cantonese speakers because pitch is already important in your first language, but English uses pitch across the whole sentence to show stress, focus, confidence, and completion.

Sentence Ending

Sentence Ending measures whether your voice falls clearly at the end of a statement. In English, many statements sound more confident and complete when the final important word lands downward.

If the app says your voice is rising, flat, or needs more drop, practice only the last word first. Then build backward into the full sentence.

Voice Tension

Voice Tension is a foundation metric. A tight or pinched voice can make pitch contour and sentence endings harder because the throat is doing too much work.

If this is your weak point, do not force the sentence harder. Do a straw exercise, lip trill, relaxed hum, or gentle airflow drill, then record again.

Biggest mismatch region

The red highlighted area on the pitch graph shows where your pitch pattern differed most from the reference. This is not saying the rest was perfect. It is simply the best place to focus first.

How to practice from the score

  1. Read the overall score once, then stop staring at it.
  2. Find the weakest metric or the “Focus for next try.”
  3. Do one drill for that issue.
  4. Record one more attempt.
  5. Compare the trend, not just one score.
