Singing Voice 1K — a raw synthetic singing collection
Singing Voice 1K is a collection of English-language synthetic singing generated with LeVo 2 in its vocal mode. It is intended as a starting point for research on singing voice and related audio models. The release contains 146,640 clips, in 128 WebDataset-style TAR shards, with English lyric and generation metadata alongside each FLAC.
The selected clips contain 1,174.92 hours of audio files, of which 1,000.01 hours exceed the run's non-silence threshold. The latter is a rough signal-level measure, not a measurement of actual singing time.
Raw research data: Basic automated checks removed some malformed lyrics, silent or invalid audio, and clips with certain cutoff problems. The collection has not undergone comprehensive content, transcription, singer-count, or musical-accompaniment filtering. Sound quality, intelligibility, solo singing and absence of instruments or backing vocals have not been fully verified. The data needs further filtering, listening, and annotation before use as a clean singing-voice dataset.
The listening grid contains 50 examples from an earlier English pilot with the same general approach; they are not a random selection from this final release. The examples below are five randomly selected clips from the final collection.
Listen to five examples
1. britpop · Triumph — male, rock, britpop, adenoidal regional-accented drawl, very high pitched, quick and urgent
2. sea shanty · Amusement — female, folk, sea shanty, hearty rolling call, very high pitched, brisk and rhythmic
3. grunge · Fear — male, hard rock, grunge, strained throaty rasp, medium pitched, slow and spacious
4. falsetto pure · Pain — male, soul, pure falsetto, light hooty unsupported head voice, very low pitched, slow and spacious
5. punk · Sadness — female, pop punk, punk, shouted snarling barked delivery, very low pitched, quick and urgent
What is in the release?
The input design spans 21 genre prompts and 40 emotion prompts drawn from the EmoNet-Face taxonomy (paper). Requested voice gender, pitch, tempo and length were varied. The final selection balances non-silent duration across genre and emotion cells and aims to balance requested voice and pitch categories. These are prompt labels, not independently verified descriptions of the sound. The generated lyrics may contain awkward language, repeated phrases, invented facts, unexpected words, sensitive content or names. A portion of short clips were cut at quiet boundaries; the supplied lyrics were not aligned to the cropped audio.
Each data/part-*.tar contains pairs en_XXXXXXX.flac and en_XXXXXXX.json. The JSON includes the lyrics supplied to LeVo, the audio description, lyric-authoring request, requested genre/emotion/voice/pitch/tempo, sampling parameters and seed, audio metrics and SHA-256. metadata/manifest.jsonl is a path-scrubbed index of the selected examples. metadata/lyric_generation.jsonl.gz contains the one-pass text-generation ledger, including rejected text candidates and their quality flags. code/ contains the path-scrubbed prompt preparation, lyric generation, audio generation, selection and packaging scripts; code/REPRODUCIBILITY.md describes the environment and source models.
Creation
We generated the lyrics with Gemma 4 12B IT, using a positive few-shot example, English noun prompts drawn from WordNet, and one-pass sampling. The audio was generated by LeVo 2 / SongGeneration-v2-large using the native vocal-generation mode. A limited set of automated checks was applied once; rejected examples were not repaired or regenerated. Selection was based on a non-silence proxy and requested labels, rather than manual acoustic verification.
Limitations and responsible use
The collection is model-generated; it is not a recording of a documented human singer. The model can still produce recognizable similarities, unintended voices, instruments, overlapping singers, nonsensical or offensive text, and other artifacts. Prompted gender, emotion and other voice descriptors are not verified identity or demographic labels. No claim is made that lyrics are exact transcripts. Users should perform their own content review, acoustic filtering, annotation and evaluation for their intended use.
