| # Apollo 11 Mission Audio — Diarized Transcripts |
|
|
| Machine-generated **transcripts with speaker diarization and timestamps** for |
| 103 tapes (175 hours) of Apollo 11 mission audio from the |
| Internet Archive's [Apollo11Audio](https://archive.org/details/Apollo11Audio) |
| collection (NASA recordings, public domain). |
|
|
| Generated in a single [Hugging Face Job](https://huggingface.co/docs/hub/jobs) with |
| [OpenMOSS-Team/MOSS-Transcribe-Diarize](https://huggingface.co/OpenMOSS-Team/MOSS-Transcribe-Diarize) |
| (0.9B, Apache 2.0) — joint transcription + speaker attribution + timestamps in one |
| generation pass per clip. |
|
|
| ## Configs |
|
|
| - **`segments`** (45355 rows): `tape`, `part`, `start`, `end`, `speaker`, `text`. |
| Timestamps are seconds from tape start. |
| - **`tapes`** (103 rows): per-tape duration, transcript coverage, parts, speaker sets. |
|
|
| ## Known limitations |
|
|
| - **ASR quality**: this is scratchy 1969 radio audio; expect mishearings |
| (e.g. "Apollo eleven" sometimes transcribed as "Follow eleven"). |
| - **Degenerate output filtered**: on long non-speech stretches (static, carrier |
| hiss, Quindar tones — and some tapes in the source collection are entirely |
| empty transfers) the model hallucination-loops. Segments that are empty, |
| dots-only, malformed, internally repetitive (zlib compression-ratio > 2.4, the |
| Whisper heuristic), or identical to >2 preceding segments were dropped; |
| compare `num_segments` vs `num_segments_raw` in the `tapes` config. Raw |
| unfiltered output is preserved in the generation bucket. |
| - **Speaker labels** (`S01`, `S02`, ...) are anonymous and consistent only |
| **within a part**: tapes longer than ~55 min are processed in clips and the |
| labels reset between them (the `part` column). Labels are not linked across |
| tapes either. |
| - **Coverage**: the model occasionally stops early; the pipeline continues from |
| the last timestamp, but per-tape `coverage_s` in the `tapes` config shows any |
| remaining gaps (170/175 h covered overall). |
|
|
| ## Reproduction |
|
|
| Generated with the [`moss-transcribe-diarize-server.py`](https://huggingface.co/datasets/uv-scripts/transcription/blob/main/moss-transcribe-diarize-server.py) recipe from [uv-scripts](https://huggingface.co/uv-scripts). The recipe serves the model with [sglang-omni](https://github.com/sgl-project/sglang-omni) inside the job and transcribes files concurrently (37.8x realtime aggregate on a100-large). Run it yourself: |
|
|
| ```bash |
| hf jobs run --detach --flavor a100-large -s HF_TOKEN --timeout 8h \ |
| -v hf://buckets/user/audio-files:/input:ro \ |
| -v hf://buckets/user/transcripts:/output \ |
| lmsysorg/sglang:nightly-dev-cu13-20260709-074bb928 -- \ |
| bash -c "pip install -q uv; git clone --depth 1 https://github.com/sgl-project/sglang-omni.git && cd sglang-omni && uv venv .venv -p 3.12 && . .venv/bin/activate && uv pip install . && (sgl-omni serve --model-path OpenMOSS-Team/MOSS-Transcribe-Diarize --host 0.0.0.0 --port 8000 --max-running-requests 16 --mem-fraction-static 0.80 &) && uv run https://huggingface.co/datasets/uv-scripts/transcription/raw/main/moss-transcribe-diarize-server.py /input /output --concurrency 6 --emit-txt" |
