It can help, but it should not be the only way to complete a permit in a noisy area. Background noise from compressors, pumps and generators makes speech recognition less reliable, and a misheard answer on a permit is a much bigger problem than a misheard search query.
Voice works best as an option for capturing descriptions and notes when someone has their hands full, with every answer shown back on the screen for the worker to confirm before it is saved. Critical fields like isolation points, gas readings and sign offs should always be confirmed visually, and anyone who prefers to type or tap should be able to do the whole permit that way.
