RadioTalk US Audio (Clean)
Synthesized clean-speech audio for ~100k US air-traffic-control conversation scenarios. One row per turn, embedded 24 kHz mono PCM_16 WAV.
This is the clean variant. A VHF-AM-channel-degraded variant is published as twangodev/radiotalk-us-audio-tada-noisy.

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-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

RadioTalk US Audio (Noisy)
VHF AM aviation channel-degraded variants of synthesized US air-traffic-control speech. One row per (clean turn × variant), embedded 8 kHz mono PCM_16 WAV.
This is the noisy variant of twangodev/radiotalk-us-audio-tada-clean — same transcripts and voices, passed through a probabilistic channel-simulation pipeline calibrated to the ATCO2 corpus SNR distribution (mean ~8 dB, range -5 to +30 dB) and shaped to ITU-R M.1084 / DO-186B aero voice passband… See the full description on the dataset page: https://huggingface.co/datasets/twangodev/radiotalk-us-audio-tada-noisy.radiotalk-us-audio-higgs-noisyradiotalk-voices-2k
radiotalk-voices-2k
2,000 English reference voices — one 12–30s clip per speaker, selected as the longest qualifying utterance per speaker from LibriTTS-R. Built for zero-shot TTS voice cloning in the radiotalk pipeline.
