Study Notes
- Creating machines to understand speech has been a lengthy process, demanding extensive research funding, time, ingenuity and raw computation.
Radio Rex
- In 1922, Radio Rex was released, a toy bulldog that jumped from its house when "hearing" its name.
- It was activated via a spring triggered by a 500-Hz acoustic energy burst, that corresponds to a vowel in "Rex".
- Adult males could trigger the toy, while an 8-year-old girl would not, unless she sounded similar to the males.
Early Speech Recognition
- Unlike Radio Rex, speech recognition needs to detect and combine acoustic dimensions.
- In 1952, "Audrey", a room-sized computer, identified spoken numbers from zero to nine, with pauses and one speaker
- After this the development of speech recognition advanced slowly, until the creation of smartphone applications.
Acoustic information
- Speech recognition involves "chunking" acoustic streams into language units.
- Languages form words by recombining a finite set of fundamental sound units, giving rise to vocabularies.
- These sound units combine relevant acoustic speech features in a messy, complex way.
- The relationship between sound abstractions and their physical appearances poses a challenge, making automated speech recognition difficult.
- Automated speech recognition is challenging because abstract language units are represented by symbols if a computing device is interacted with by typing.
Speech Perception
- Translating speech sounds, which are elusive, into stable representations is a challenge for humans.
- Speech perception requires both stability and flexibility
- Listeners structure information by overlooking irrelevant acoustics or attending to details when relevant.
- People adjust to speech based on the speaker's differences in accent and the surrounding environmental conditions.
Variability of Sounds
- The tongue and mouth constrain spoken language by gestures, shapes, and movements.
- Sounds smear properties onto one and another, not having orderly spaces like letters.
- Signed language is analogous, where each 'sound unit' is performed at a body location, with transitions between these gestures lacking clear boundaries
Coarticulation Effects
- Variability arises from coarticulation effects and different vocal tracts; identifying definite acoustic properties that map to sounds is hard.
- Coarticulation: The pronunciation variation of a phoneme affected by properties from neighboring sounds.
- Perceptual Invariance: How is it that acoustic input can be mapped to representation?
- Perceptual Invariance: Perceiving sounds with highly variable acoustics as instances of a sound category.
The Mind
- The mind imposes structure on speech sounds as a result of learning.
- Similar sounds carrying the function are grouped into 'phonemes'.
- Phonemes break down into 'allophones', understood as part of the same class.
- Phoneme: Smallest sound unit changing a word's meaning, an abstract unit related to possible pronunciations.
- Allophones: Similar sounds that are variants of a phoneme.
Sorting Categories
- Perceptual warping may be beneficial, mental structure may amplify acoustic differences while minimizing the others.
- Perceptual warping allows ignoring insignificant sound differences.
Linguistic Properties
- Speech sounds are grouped on how they are articulated like consonants, which is characterized by dimensions.
- Place of articulation refers to where airflow is blocked.
- Manner of articulation signifies extent of airflow cutoff.
- "State of the glottis" signifies the presence of vocal fold vibration.
Variability of signed language
- Variability in some ASL sources are: coarticulation effects, production speed, individual signer differences, age, and geographical location.
- Challenges in visual: Visual Orientation, visual info masking.
Voicing
- Voicing distinguishes voiced stop consonants like /b/ and /d/ from their voiceless counterparts /p/ and /t/.
###Categorical Perception
- The idea is that vocal categories impose sharp boundaries.
- Sounds in a phoneme category are perceived as, even if differing, while sound across the boundaries differ in ways.
- Differences can be perceived even when subtle
Forced choice identification task
- Categorize stimuli falling into one of two categories despite the uncertainty.
Adaptation-Signed language
- It is easier to determine the differences between two fingers when the gap is very small
- Those with more experience in sign language were less sensitive to "U" signs than those less experienced.
Speech Perception
- Humans can sort sounds accurately.
- One possibility is humans can amplify acoustic differences between sound and minimise others. Mental categories actually warp perception.
Speech Recognition
- In 1922 Radio Rex toy released, springs activate with 500hz of acoustic energy.
- Rex would obey adult males who contain the targeted vowel.
- In 1952 "Audrey" was able to speak recognizing numbers zero to nine.
- The relationship between abstractions and physical manifestations is complex.
Multiplicity-Sounds
- Mental structure amplifies, while minimizing others with sound; The mental is what shapes speech.
Continuous Perception
- Judgements bout the gradually identity change.
Categorical Perception
- Judgements about which sound abruptly shift.
Voice Onset TIme(VOT)
- English Voice sound(ba) can occur at Vot of 0 ms. Where as a typical unvoiced may sound at 60ms.
Categorical Perception
- Assigning categories to continuous sound.
Speech studies
- Many studies are to see if sounds. A study led by MC Murray to see often experience sounds.
Adaptive learning
- Adaptive comes from hearing accents. Five native people from each background listened to these lines, so their minds can change a bit.
Web Activity 7.1
- Testing the limits of Automatic Speech regonition
- Web activity 7.2: Variability in signed language.
- Web activity 7.4: Phoneme restoration.
Motor theory
- Inability to process movement.
Gestural representation
- Gestural representation for the daily task of speech of perception is complex and there is a disagreement on it.
Phoneme Restoration Effect
- Non-speech sounds share acoustic with sound is heard w/ expectation.
McGurk Effect
- Vision and auditory information affects the way we speak and is the reason why it causes to believe the sound.
Inability-To See
- Auditory or visually makes humans perceive with different aspects and what is heard depends on what and why, and also to have to do with a lack of motor capabilities.
Speech adaptation
- People can adapt to language and voices overtime.
- Tuning for speech, sound, and to talker.
