HOW IT WORKS
A good, clear voice recording is important for accuracy. Here's how to get the cleanest recording and measurement.
- •
Find a quiet place. Loud background noise impacts accuracy.
- •
Hold your phone 6 inches from your mouth. Slightly to the side so you don't breathe directly into it.
- •
Speak naturally for 35 seconds. Describe your environment in detail. Do not read anything.
- •
Use normal conversation volume. Not too loud, not too quiet.
