Spontaneous long-form Cebuano with human transcription and word-level forced alignment. Fifteen speakers, mean clip length over two minutes, 27,000+ timestamped tokens. Part of the Silencio Philippines Pack.
| Hours | 3.48 |
| Clips | 90 |
| Speakers | 15 |
| Countries | 2 |
| Speaker origin regions | 4 |

Splits
Single split, test, 90 rows. No train/dev/test partition is
provided: at this scale a partition would leave each part too small to be meaningful. Speaker
identifiers are stable, so a speaker-disjoint split can be constructed at load time.

Related Cebuano and Philippine speech resources
Cebuano (Bisaya, Binisaya) has roughly 20 million speakers across the Central Visayas, Negros Oriental and much of Mindanao — the second most widely spoken language in the Philippines. Existing Hub coverage:

There is no single-language Cebuano audio dataset on the Hub. FLEURS is the closest usable resource and is read speech in short utterances; this release is unscripted long-form speech with per-word timings. The two are complementary rather than competing — FLEURS for read-speech benchmarking, this for spontaneous-speech behaviour.
Also from Silencio. Tagalog / Filipino is published under this same protocol — spontaneous speech, human transcription, word-level alignment. Hiligaynon and expanded Cebuano follow; see SilencioNetwork.
Transcription and alignment
Two distinct provenances, kept separate because they carry different confidence.
Text — human. Every transcript was produced by a human annotator listening to the
recording. The transcript_model column records this per clip.
Timings — machine. Word-level start and end times come from forced alignment with
wav2vec2_mms, recorded per clip in the aligner column. On every clip in this release the
aligner's token count matches the human reference token count exactly, and no word timing
runs past the end of its audio file.
The words column holds one entry per token with text, normalized_text, start and
end in seconds. Expand it for segment-level work:
ds = load_dataset("SilencioNetwork/cebuano-speech", split="test")
row = ds[0]
for w in row["words"][:5]:
print(f"{w['start']:6.2f}-{w['end']:6.2f} {w['text']}")
Speaker proficiency
Cebuano proficiency is taken from each contributor's own declared language profile, not inferred from a single primary-language field. Most contributors here are natively bilingual: their primary declared language is Tagalog, and they also declare Cebuano at native level.
| Declared Cebuano level | Speakers | Clips | Hours |
|---|---|---|---|
| native | 11 | 65 | 2.16 |
| fluent | 3 | 19 | 0.82 |
| conversational | 1 | 6 | 0.50 |
Filter on native_speaker, or on proficiency for finer control.
What this is useful for
- Spontaneous-speech ASR evaluation. Long-form unscripted Cebuano with human reference text. Models tuned on read speech typically degrade sharply here; that gap is the point.
- Forced-alignment and VAD work. 27,000+ word-level timings over 3.5 hours.
- Long-form segmentation. Mean clip length 139 s, with several clips over four minutes. Most Philippine-language audio on the Hub is short read utterances.
- Code-switching and borrowing. Spontaneous Cebuano from bilingual speakers contains substantial Tagalog, Spanish and English material. Not annotated as such in this release.
Limitations
- Sample scale. 90 clips, 15 speakers, 3.5 hours. Enough for evaluation and for alignment work; not a training corpus.
- Speaker origin is concentrated in this sample. Every contributor here records a Metro Manila or English-speaking origin — natively bilingual Cebuano speakers based outside the Cebuano-speaking regions. That is a real and commercially relevant population, but it is not in-region recording. Contributors based in the Central Visayas and Mindanao are present in Silencio's wider Cebuano inventory and reachable through the collection programme described below; they are simply not in this sample.
- Proficiency is self-declared and not independently assessed.
- Word timings are machine-generated. Forced alignment with
wav2vec2_mms, not manually corrected. Token counts reconcile exactly against the human reference on every clip, but individual boundaries have not been human-verified. - Unbalanced contribution. Clips per speaker ranges from 5 to 7.
- No acoustic annotation. Recording environment, background-noise class and SNR are not annotated. Available for commissioned collection.
- Mixed audio format. Source audio is shipped untouched at its captured sample rate and channel count — see the spec table. Resample and downmix before batching.
- No diarisation. Single speaker per clip. Multi-speaker material is part of the collection programme described below, not this release.
- Pseudonymous speakers.
speaker_idvalues are pseudonyms, coherent within this dataset, deliberately not linkable to speakers in other Silencio releases. - No baseline. No reference WER is published with this release.
Provenance and consent
Every recording is contributed by an opted-in participant through the Silencio app, under a consent record covering AI/ML training use. Contributors can request deletion, and deletion propagates to downstream releases. Full provenance documentation is available to licensees.

Silencio corpus and collection network
Two distinct figures, because they answer different questions.
Recorded and available off the shelf — audio already collected, with metadata, licensable today:
| Hours recorded | 127,793 |
| Recordings | 9,392,870 |
| Contributors who recorded | 222,145 |
| Languages | 156 |
| Countries and territories of origin | 216 |
Contributor network available for commissioned collection — registered, consented contributors who can be activated for a specific brief. These are not active contributors to the corpus above; they are the pool it is drawn from and extended through:
| Registered contributors | 2,000,000+ |
| Countries | 180+ |
| Languages reachable | 250+ |
