SpeechTranscriber not providing audioTimeRange for most results

I started playing which transcription of audio files on macOS today, latest beta of Xcode and latest beta of Tahoe. Transcription itself works really well, but for some reason the majority of the results contain no audioTimeRange. I got 22 single-word results with time ranges, spread out all over total file of 53 minutes.

Is there something I can do to improve this? To my understanding, I have followed sample code and instructions very closely, but the SwiftTranscriptionSampleApp and other examples I've seen lead me to believe I should be getting a lot more time ranges than I actually do.

Updating to Xcode beta 5 and today's Tahoe beta made no difference, I might add.

Can you file a radar? In MacOS Tahoe beta 5, you should be seeing:

final results with word-level(-ish) audioTimeRange attributes
volatile results with an audioTimeRange attribute on the result's entire string equal to the result's range.

I'm going to try and refine my project some more first, I found another project (Yap) which gets all the ranges I expect for the same file, so I'm hopeful I've simply missed something in my setup.
