Accelerating transcription

The Transcription Acceleration Project (TAP) is a Centre of Excellence for the Dynamics of Language (CoEDL) cross-disciplinary project aimed at identifying the workflows of linguists and language workers during transcription, and developing assistive tools to accelerate that process.

Tasks such as transcribing recorded audio can be very slow. Using contemporary software techniques such as speech recognition, we can improve the the transcription experience, resulting in practical and psychological benefits for people's work.

Technologies such as Google's Cloud Speech can transcribe 100+ of the world's languages, but these tools don't support any endangered languages. For languages with small quantities of data, or for research situations which prohibit the use of cloud technologies, TAP is developing Elpis, a tool to obtain a first-pass transcription on untranscribed audio. This best-guess is used as a canvas for the language worker to refine. Elpis brings cutting-edge speech recognition technology within reach of language workers and researchers who don’t have backgrounds in speech engineering. With Elpis, we hope to enable community members to make a significant impact on transcribing their own languages from new recordings, or breath life into archival, cultural heritage material.
