 Rl1JqbNu1A4jTn2 \n\nAfrican American Vernacular English (AAVE) is by far 
 the most studied variety of American English\, yet most non-linguists eit
 her ignore or deny it\, or notice it only when it is the source of nation
 al controversies in education\, as it was in the 1996 Oakland Ebonics fir
 estorm.\n\nRecently\, however\, it became an issue of concern when Koenec
 ke et al (2020) showed that the Automated Speech Recognition (ASR) system
 s used by Amazon\, Apple\, Google\, IBM and Microsoft had on average twic
 e as many errors when transcribing the speech of black speakers as they d
 id when transcribing the speech of white speakers.\n\nIn this talk Profes
 sor Rickford will discuss what AAVE is and explain some of the challenges
  its pronunciation and grammar represent for the ASRs of Apple and other 
 systems.  He'll actually begin with a parallel example of the difficultie
 s that AAVE as spoken by vernacular black speakers pose for jurors and co
 urt reporters\, drawing on a sample of the speech of Rachel Jeantel of Mi
 ami (Rickford and King 2016).  Rachel was a good friend of Trayvon Martin
  and was the prosecution star witness in the trial of George Zimmerman fo
 r Trayvon's murder in 2012.  Discussing her speech will demonstrate some 
 of AAVE's features and demonstrate that they are systematic and rule-gove
 rned\, as is true of ALL languages and dialects.  \n\nFrom there we will 
 proceed to examples of actual speech snippets used to test the ASRs of Ap
 ple and other systems\, illustrating some of the specific difficulties th
 ey caused.  We will also introduce limited evidence of difficulties that 
 ASRs faced with Latino English and discuss possible solutions to these re
 current limitations with ASR devices.
