Using Pitch Analysis
My Voice includes built-in pitch analysis that measures the fundamental frequency of your voice each time you record. This guide explains how to read your results and use them to track progress. This feature requires a Cracking or Hatched subscription.
How Pitch Analysis Works
When you save a voice recording, My Voice processes the audio to detect the fundamental frequency — the base frequency at which your vocal cords vibrate. This is measured in hertz (Hz) and is commonly referred to as your pitch.
The analysis runs automatically on every recording, so you do not need to do anything special beyond recording and saving.
Reading Your Results
Each recording displays the following:
- Average pitch — The mean frequency across the entire recording, measured in Hz. This is the most useful single number for tracking changes over time.
- Minimum pitch — The lowest frequency detected. This often corresponds to the ends of sentences or relaxed speech.
- Maximum pitch — The highest frequency detected. This may occur during emphasis, questions, or emotional expression.
- Pitch graph — A line graph showing how your pitch moved throughout the recording. Peaks and valleys show your natural intonation pattern.
Understanding Pitch Ranges
Gender-typical ranges are shown on your pitch graph as reference bands:
| Range | Frequency |
|---|---|
| Feminine | 160–300 Hz |
| Androgynous | 120–180 Hz |
| Masculine | 80–150 Hz |
These ranges overlap intentionally — there is no sharp boundary between them. Many people have a natural pitch that sits between ranges, and that is perfectly normal.
Tracking Progress Over Time
The real value of pitch analysis comes from comparing recordings across weeks and months:
- Go to My Voice and view your recordings timeline.
- Select any two recordings to compare their pitch data side by side.
- Look at how your average pitch has shifted over time.
Changes in voice pitch can be gradual, especially during the early months of voice training or hormone therapy. Regular recordings — even once a week — give you enough data to see meaningful trends.
Tips for Accurate Results
- Record in the same conditions — Same room, same microphone, same time of day if possible.
- Speak naturally — Do not try to force your voice higher or lower than comfortable. The goal is to track your natural speaking voice.
- Record for at least five seconds — Short recordings may not capture enough data for accurate analysis.
- Minimise background noise — Background sounds can interfere with pitch detection.
