A ropewalk loft updates Riva ASR site vocabulary, microphone gain, and the language pack in one weekend, then reports that recognition “got better.” What is the soundest next experimental move?
Select an answer to reveal the explanation.
Short Explanation
Changing vocabulary, gain, and language pack together is like adjusting three knobs and guessing which one fixed the radio. A valid ASR A/B moves one factor and holds the evaluation audio fixed. Same utterances, one change—then you know what helped.
Full Explanation
Controlled ASR customization experiments isolate a single variable—vocabulary, acoustic settings, or language pack—while replaying the same evaluation utterances. When three factors move at once, any word-error drop is uninterpretable. The next trial should restore single-factor control before claiming Riva improved.
