The phrase "doth number on" is an archaic way of saying "continues to count". The spelling of "doth" is pronounced as /dʌθ/ where the "th" is pronounced as the "th" sound in "thin". This is commonly referred to as a voiceless dental fricative. "Number" is spelled as /ˈnʌmbər/ with the stress on the first syllable and the "b" is pronounced, unlike in some dialects where it may be silent. "On" is pronounced as /ɒn/, with the final "n" sound in "on" often being elided in speech.
