Isochrony is the idea that a leid rhythmically divides time intae equal portions. Three types o diveesions are postulatit:

  1. the temporal duration atween twa stressed seellables is equal (stress-timed);
  2. The duration o ivery seellable is equal (seellable-timed);
  3. the duration o ivery mora is equal (mora-timed).

The idea wis first expressed bi Ken Pike in 1945. While mony linguists find the idea o different rhythm types appealin, empirical studies hae no been able tae fynd acoustic correlates o the postulatit types, cawin intae quaisten the validity o thir types.[1][2][3]
