How do I compare two speaking apps fairly?

Use one scripted sentence, record both attempts in the same room on the same phone, and score four things: detection, naming, the fix and the retry. Anchored criteria matter more than a long feature list, because features describe the product while the four criteria describe what it did to your speech.

Use one scripted sentence, one room, one phone, one attempt per app, and score detection, naming, the fix and the retry out of five each. The controlled conditions do more for fairness than a longer list of features.
