Code-switching in speech, the process of switching from one language to another
in the same conversational sequence, is common in bilingual and multilingual
communities and has been receiving growing attention in the speech and language
communities. The language switch can be just the incorporation of words or
short phrases from another language, or can be at a speaker turn or even larger
level. The video of our
workshop presentation describes our participation in the
shared task challenge organized by Microsoft Research on language identification
(LID) of code-switched speech in three language pairs: Gujarati-English,
Telugu-English and Tamil-English.
Vocapia, together with LIMSI-CNRS, have
been developing and participating in evaluations of LID technologies for more
than a decade. We have extensively explored a variety of approaches including
phonotactic and acoustic ones, e.g.
[Odyssey 2016] and
[InterSpeech
2016]. LIMSI also addressed Code-Switching in French/Algerian Arabic
Speech [Interspeech 2017].
Our submissions to the Microsoft challenge were ranked first in both LID
tasks: the first (task A) detecting if a given utterance was monolingual or
contained code-swithing; and the second (task B) ) producing a frame-level
language labeling of code-switched speech.
Vocapia Research is a French R&D company and software publisher with over
20 years of experience in providing leading edge speech technologies for many
languages, including most major European languages as well as Arabic,
Mandarin, and Russian. The Vocapia Research VoxSigma
® software
suite uses advanced language technologies such as language identification,
speech recognition, and speaker identification to transform raw audio and
audiovisual data into structured and searchable XML documents. This technology
relies on decades of research at LISN, with which there is a privileged
partnership. Joint systems developed with LISN have achieved top ranks in
national and international challenges on speech-to-text transcription. Located
at the heart of the science innovation cluster of Paris Saclay, France,
Vocapia Research is a leader in developing and adapting AI-based solutions for
both civil and defence applications. These applications include audio and
audiovisual data mining (broadcast and web data, telephone speech), production
of subtitles, OSINT and COMINT, and the analysis of aeronautical
communications (air traffic control, voice command). Readers who wish to get
