Information about TIMIT

Here are some stop releases in TIMIT that illustrate unusual behavior.

Format: sentence -- time -- apparent articulatory events

  • Transient and Frication
    • Multiple Bursts
      • fsdc0/sx52 - 2010 - four bursts.
      • mwem0/sx240 - 2757 - five bursts.
    • Gradual Fricated Releases
      • ...too numerous to mention...
      • mmdb0/sx87 - 327 - gradual frication onset, with a strong peak 15ms after frication onset.
    • Pre-Frication, then a Transient
      • mesj0/si997 -- 2978 -- /b/ae/
      • fsdc0/si2234 -- 869 -- strident frication.
      • fpmy0/si1153 -- 3334. ftaj0/sx69 -- 1877.
      • mrld0/sx424 -- 2032. mrws1/si1130 -- 1542.
      • mrxb0/sx55 -- 1713 -- early burst, frication, second burst.
      • fjsa0/si749 -- 4996 -- voice offset before closure, frication burst at closure.
    • Stop Implemented as a Fricative
      • mjrb1/sx300 -- 4198 -- /k/ in /s/k/uw/ implemented as a strident velar fricative.
    • Glide Implemented as a Fricative
      • mrab0/sx54 -- /p/, then rounded fricated /y/, then /y/.
  • Voice Source
    • Diplophonia
      • mrwa0/sx253 -- /g/er/. mdlm0/si1234 --/b/ax/.
    • Filled Pauses
      • mmds0/sx83 -- /d/ released into a high-pitched "squeak" pause (with /ah/ quality of following vowel).
      • fpjf0/si1259 -- 2321 -- /p/ released into a high-pitched boundary marker.
      • mmea0/si758 -- 2202 -- "filled pause" (one glottal pulse) inserted in the middle of frication for a /k/.
    • Drop Shut" Voice Onset
      • mjwt0/sx31 -- 319.
      • mkrg0/sx31 -- 276.
      • fmpg0/sx342 -- 3633.
      • mmag0/si496 -- 277 -- clearly a glottal pulse, but sounds like a /g/ burst.
      • mjdm0/sx350 -- 3879.
    • Other voicing or pulses during aspiration
      • mpab0/sx318 -- 1012 -- /p/ih/ -- glottis closes and opens, then vibrates slowly for 17ms until the next closure.
      • freh0/sx55 -- 1573 -- voicing, about 15ms.
      • mfrm0/sx435 -- 2418 -- strong glottal closure, with F1 ringing, 14ms before next closure.
      • mgjc0/sx435 -- /t/eh/ -- strong peak, looks like a second burst, but sounds like aspiration.
      • fsjg0/sx40 -- 432 -- big peaks 15ms after burst, sound like aspiration.
    • Oral cavity changes voicing
      • mkrd0/si1903 -- 1580 -- tongue release changes the voicing waveform (impulsive closure) 4ms before the "burst."
  • Place of Articulation Effects
    • Double Articulation
      • mwew0/si1361 -- 0.15 -- /b/ax/ -- implemented as a labialized glottal stop.

      • mslb0/sx203 -- 1344 -- doubly articulated labial/alveolar, bursts 9.3ms apart.
    • Reduction of /t/
      • mrso0/si1206 -- 1185 -- /t/ in "stood" becomes /th/; sounds like /k/ if you play it alone, but sounds like /th/ if you add the /s/ or the /uh/.
      • mjrb1/sx300 -- 2196 -- second /t/ in "constantly" implemented as a lateral velar release.
    • Reduction of /d/
      • flag0/si2094 -- 936 -- to /dh/ after /l/.
