This is an adapted and reorganized Evenki data from AIRI's AI4TALK competition. It is intended for automatic speech recognition: each row identifies a speech segment in an MP3 file and provides an IPA-like transcription. Audio files are stored in `audio/`, and `asr.csv` references them with relative paths. The original AI4TALK language code and recommended MDC locale are both `evn`. Evenki is a Northern Tungusic language spoken in eastern Russia and China, with roughly 17,000 native speakers according to Wikipedia's current infobox.
