7/3/2023 0 Comments Speech perception definition![]() Strange, Edman, and Jenkins (1979) performed a study in which people tried to identify vowels in different conditions and pairings (i.e., paired with different types of consonants in different orders). However, in continuous speech, the cues used to identify vowels rely on the transition between the vowels and the consonants. ![]() Consonants have certain properties encoded – for example, an unvoiced consonant is encoded differently than a stop consonant. For example, a person cannot make the sound of a consonant (i.e., k) without expressing a vowel sound with it. Consonants cannot be perceived without an accompanying vowel, but they sound shorter and require less energy to produce. However, the sound of a vowel is strongly influenced by the sounds around it. When isolated, vowels have a long, steady quality. Vowels and consonants are identified differently.

And yet, without being able to separate these individual words, people are able to understand a whole stream of these sounds that are almost unidentifiable in isolation, and make sense of them. We can never really segment thoughts into different phonemes, because their property of invariance causes them to blend together. Our perception of continuous speech is different from our perception of individual words, because it is affected by the individual words and phonemes. The perception of speech segments and continuous speech is a truly incredible feat of the human mind. Without being able to comprehend continuous speech, we would be unable to understand what others are expressing – we would be isolated. Our ability to put together and understand continuous speech is what makes communication possible. Whether we are listening to a friend’s funny story, or to a powerful political speech, we use the steps involved in understanding of the stream of language that allows us to communicate with others. The perception of continuous speech is a complex and difficult process.
