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 empty-text turns in the source transcripts.
Schema matches the earlier audio releases
(higgs /
tada);
tts_model reads grok-tts. For the VHF-AM channel-degraded counterpart see
twangodev/radiotalk-us-audio-grok-noisy.
Intelligibility (Grok STT)
10,000-utterance sample transcribed with Grok STT and scored against the source text: 5.8% mean WER, 0% median, 75% exact matches. The noisy counterpart degrades this to 41.8% mean WER.
