In this paper, we study the influence of the vocalic context on the perception and automatic recognition of stops. In a previous perception experiment [1] using conflicting cues stimuli, we have shown that place of articulation cued by formant transitions may be overwritten by the place cued by the burst. This effect is inversely proportional to the vowel aperture. Here we give special attention to /i/ context where nor burst, nor formant transitions seem to carry rich information on place of articulation. We present here automatic recognition experiments that confirm perception results. Taking into account both segments increase identification rates, early fusion of segmental cues performs best and most errors come from the front unrounded vocalic context. We introduce the "burst characteristic frequency" (BF) that palliates for the poor discriminative power of the traditional cues in the front context. Moreover we present perception results showing the perceptual relevance of BF.
