How accurate is AI transcription for construction and technical terms?

SiteSurvey AI transcription handles construction and technical terminology accurately by using a custom vocabulary layer that covers common trades, building materials, industry standards, and regulatory references used in UK construction and facilities management.

General-purpose transcription engines frequently mis-transcribe terms such as "DPC", "soffit", "spandrel panel", or references to specific British Standards. SiteSurvey addresses this by maintaining a sector-specific vocabulary that is updated regularly and can be extended with organisation-specific terms through the admin settings.

In testing across construction and FM survey types, transcription accuracy for technical vocabulary consistently exceeds 95 percent for clearly spoken notes in normal ambient conditions. Accuracy can be affected by heavy background noise from plant machinery or high winds, so the app provides an audio level indicator to help surveyors record in suitable conditions.

Any term the AI is uncertain about is highlighted in the transcription review screen so the surveyor can confirm or correct it before the note is committed to the report. This review step takes seconds and protects data quality without requiring surveyors to retype notes from scratch.
