The pause between names

An original account of an invented recording session.

We were recording the names of the streets for a walking guide. Everyone expected the longest names to cause trouble, but it was the silence between them that took time. On our first attempt, the final sound of one name ran into the beginning of the next. A listener might reasonably have thought that two streets were one.

The producer asked us to leave a brief gap after each name. She called it a pause, not an ending: the listener should have time to recognise a place without thinking the recording had stopped. We practised the gaps several times. By the end, I was paying as much attention to what we did not say as to the words themselves.

In this account, what is meant by “ran into”?
