What the data for this category looks like
The data for this category primarily comes from uploaded audio files, annotation platform annotation results, custom term lists, and spot-check samples. Daily associated documents include transcription specifications, audio lists, quality inspection reports, and speaker annotation forms. Data is updated daily or synchronized per annotation batch. A single data entry includes fields such as audio ID, transcribed text, speaker markers, noise segment judgment results, and custom term verification status. The overall workflow first converts audio content into structured text, then performs annotation and verification, which differs from the data sources and processing order of plain text annotation projects.
How these characteristics impose constraints on the conversation logs and auditing link
The data sources for speech annotation and transcription include audio files and associated information from annotation platforms. This requires that conversation logs must be bound to both audio IDs and annotation batch IDs to enable full-link traceability of individual audio files. The batch-based data update characteristic requires logs to be archived per batch to facilitate subsequent batch retrospectives and quality inspection traceback. The existence of speaker annotation forms requires the auditing link to verify the consistency between speaker markers in logs and the annotation forms, to identify annotation deviations. The core time-consuming links of noise judgment, speaker differentiation, and custom term proofreading require logs to record intermediate step data for these links; retaining only final results is insufficient to support precise troubleshooting.
How to configure settings
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
chatId | Unique identifier bound to annotation batches | Links full-link conversation logs for a single batch of speech annotations, facilitating batch retrospectives |
responseChatItemId | Sub-item ID generated per audio file ID | Locates transcribed and annotated conversations for individual audio files, enabling precise tracing of error sources |
detail | Includes noise segment markers, speaker matching results, custom term verification results | Covers auditing details for core speech annotation links, supporting targeted troubleshooting |
| Log storage period | 30–90 days | Matches the delivery and retrospective cycle of annotation batches, balancing storage costs and auditing needs |
| Exception log sampling rule | Prioritize recording entries with transcription confidence <0.7 | Focuses on high-risk annotation links, improving troubleshooting efficiency |
Three common misconfigurations
- Symptom:
ocr errorerror message appears in logs. Cause: Noise filtering threshold for audio preprocessing was not specified in the configuration, causing invalid audio segments to trigger OCR recognition failure. - Symptom: No corresponding log entry appears after calling the transcription interface, even though the transcription operation has completed. Cause: Associated fields for the
detailparameter were not properly configured, preventing the log writing process from triggering. - Symptom: An error indicating missing parameters occurs when regex matching chat record fields. Cause:
responseChatItemIdwas not bound to the unique identifier of chat records, causing valid parameters to not be obtainable during matching.
How to confirm configuration is complete
- Generate a test audio transcription conversation with clear noise markers, check whether the logs include detailed information such as noise segments and speaker matching corresponding to the
detailfield. - Input a test case with a known speaker annotation error, verify whether the
chatIdin the logs is correctly associated with the preset annotation batch identifier. - Trigger an abnormal process with transcription confidence lower than 0.7, check whether logs are generated and include the audio identifier corresponding to
responseChatItemId. - View the log storage directory of FastGPT v4.17.0, confirm that the archiving period meets the preset 30–90 day requirement.
