The place-name recording session

Five errors have been introduced into this notice.

Volunteers are invited to record the names of lanes, fields and footpaths for a local language project. A brief practise will be offered before the recording starts. Each participant should check there microphone before the session begins. A list of place-names have been prepared, but contributors may suggest others. Please speak clearly, leave a short pause after each name. The recordings will be stored securely and used only with each contributors permission. If background noise affects a recording, it can be made again.

Proofread the notice. Identify the five errors and write the correct forms. You do not need to rewrite the whole passage.
