radiotalk-us-audio-grok-noisy
radiotalk-us-audio-grok-noisy
VHF-AM channel-degraded counterpart to
twangodev/radiotalk-us-audio-grok-clean:
3 independently-degraded variants per clean utterance (bandpass, noise,
fading, heterodyne, PTT clicks, codec artifacts — the same radiotalk radio
pipeline behind the higgs/tada noisy sets). 1,583,103 rows covering all rendered scenarios of
twangodev/radiotalk-us-transcripts-grok-4.20-50k.
Difficulty (Grok STT)
On a 10,000-utterance sample, Grok STT scores… See the full description on the dataset page: https://huggingface.co/datasets/twangodev/radiotalk-us-audio-grok-noisy.radiotalk-us-audio-grok-clean
radiotalk-us-audio-grok-clean
Clean TTS audio for the v3 radiotalk transcripts: one row per transmission,
24 kHz mono PCM_16 WAV. Covers all 49,975 rendered scenarios of
twangodev/radiotalk-us-transcripts-grok-4.20-50k
— 527,701 utterances in uniform 1,250-row shards.
Synthesis: xAI Grok TTS API, 26 preset voices. Each scenario's speakers get
a deterministic voice assignment (seeded by scenario id) and a fixed
per-speaker speaking rate in 1.0–1.3×. 9 scenarios were dropped for… See the full description on the dataset page: https://huggingface.co/datasets/twangodev/radiotalk-us-audio-grok-clean.radiotalk-us-transcripts-grok-4.20-50k
radiotalk-us-transcripts-grok-4.20-50k
49,984 synthetic US air-traffic-control transcripts, generated with
xAI's grok-4.20-0309-non-reasoning against the v2 radiotalk scenario
pipeline. Built for fine-tuning ATC ASR models (NVIDIA Parakeet,
Whisper, etc.) and for seeding TTS audio generation.
Third release in the radiotalk transcripts series, and the first from a
non-Qwen generator:
v1: twangodev/radiotalk-us-transcripts-qwen3-100k
v2:… See the full description on the dataset page: https://huggingface.co/datasets/twangodev/radiotalk-us-transcripts-grok-4.20-50k.radiotalk-us-transcripts-grok-4.3-25k
radiotalk-us-transcripts-grok-4.3-25k
24,995 synthetic US air-traffic-control transcripts, generated with xAI's
grok-4.3 (reasoning) against the same v2 radiotalk scenario pipeline as
the earlier releases. Fourth release in the series:
v1: twangodev/radiotalk-us-transcripts-qwen3-100k
v2: twangodev/radiotalk-us-transcripts-qwen3-25k
