Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might have been a recent update. Has there been any significant software or model changes in the past month?

Why it matters: Recent changes could directly impact transcription accuracy. Expected answer: Yes, there was a model update. Impact on approach: If confirmed, we'd focus on the update's specifics and rollback options.

• Considering user segments, I'm curious about the distribution. Is this accuracy drop consistent across all user types or more pronounced in specific segments?

Why it matters: Helps identify if the issue is universal or segment-specific. Expected answer: The drop is more significant in non-native English speaker segments. Impact on approach: We'd investigate language model biases and accent handling.

• Thinking about data quality, has there been any change in the audio input sources or quality in the last month?

Why it matters: Audio quality directly affects transcription accuracy. Expected answer: No significant changes in audio sources. Impact on approach: If confirmed, we'd focus more on internal system issues rather than input quality.

• Considering system health, have there been any infrastructure changes or unusual load patterns recently?

Why it matters: System performance can impact AI model efficiency. Expected answer: There was a recent cloud migration. Impact on approach: We'd investigate potential issues related to the new infrastructure.
