aic_test_calls_en
An evaluation dataset of real far end call recordings for accurate speaker transcription under realistic conditions.
The dataset provides around 35 minutes of genuine team and test calls recorded at ai-coustics, captured under real-world acoustic and transmission conditions — real rooms, real devices, real meeting and telephony channels — together with human-produced ground-truth transcripts. No clean speech reference exists; evaluation is transcript-based.
Dataset Description
Direct Use
This dataset is intended for evaluation of speech processing systems on genuine call audio in conditions relevant to downstream speech-to-text systems.
Technical Details
- 83 clips with a total duration of 00:35:29 [hh:mm:ss]
- Minimum duration: 5.54 s
- Maximum duration: 54.44 s
- Mean duration: 25.65 s
- 16 kHz sampling rate, 16-bit, mono
- 4 speakers, all recorded with informed consent
- Voice gender distribution: 64 % female-sounding voices, 36 % male-sounding voices (2 of 4 speakers each)
Dataset Structure
Each row in the dataset contains the following fields:
mix: 16 kHz WAV audio of the call recordingtranscript: Ground-truth transcription corresponding to themixaudioid: Opaque unique sample identifier (random short uid)speaker_id: Numeric identifier of the primary speakerindex: Integer index distinguishing multiple samples from the same speaker
Dataset Sources
Audio
- Segments of dedicated test calls recorded in different locations
- Captured through the recording features of the call platforms and receiver devices. The acoustic conditions (rooms, background sounds) and transmission effects (codecs, network) occurred naturally during the calls.
Transcriptions
- All transcripts are quality-checked by AIC staff.
