Pitfalls

Learn in five minutes

• A fluent transcript can still have the wrong word. Check it against audio you are allowed to hear.
• Wikipedia's sentiment page lists metaphor, differences in writing, and context as reasons a class can change.
• Precision and recall, on the speech-analytics page, answer different questions. Report which one you computed.
• A redaction that deletes the name and keeps a unique account number has not removed the identifier.
• Do not paste a real customer's recording into this lab.

Each pitfall has a check you can do on a toy line. None of them is fixed by a more confident sentence.

Four checks

1. Transcript: compare one word with the audio, or write 'no audio, no word-error claim.'
2. Sentiment: write the context that could flip the label.
3. Search: write whether you computed precision or recall.
4. Redaction: search the line for a number you left behind.

Ecosystem

Pitfall

A failure mode named by a source. It is not solved by a fluent sentence.

Sisters: Automatic speech recognition, Sentiment analysis, Quality rubrics, Personal data.

The live voice pipeline answers the person. Analytics reads a recording later. Keep those clocks apart.

A later review can add a rubric you wrote. It cannot borrow a customer's tape.

Config

• Write the goal in one sentence.
• Name the input and the allowed output.
• Save the trace next to the result.

Troubleshooting

• The answer looks fluent and is wrong. Check whether a source passage actually contains the claim.
• The loop never stops. Set a step cap and stop when the tool result repeats.
