The issue here may be that there is no rigid terminology for discussing methods of transcribing technical material.

I suggest that when absolute clarity is needed, the following phrases be used:

• “transcribed according to UEB Guidelines for Technical Material”
  • (which means NO Nemeth is used)
• “transcribed according to the “Provisional Guidance for Transcription Using the Nemeth Code within UEB Contexts” or “transcribed according to the “Guidance for Transcription Using the Nemeth Code within UEB Context”
  • (which means Nemeth is used, within Nemeth switch indicators)
