How important is stability in your speech measures? Have a look here how we tested reliability, stability and sensitivity to change in vowel measurements. Our new study published in the prestigious Journal of the Acoustical Society of America – out today!

Some take-away points:
1. Some metrics are stable, but insensitive
2. Some metrics are unstable and sensitive
3. The only measures we should be using in treatment trials are both stable in the absence of change and sensitive to different conditions known to alter performance.
