+# Mixed-Language Speech Detection Pilot
+
+This dataset is a 6,000-clip binary audio-classification pilot for detecting
+whether an utterance contains one language (`label = 0`) or more than one
+language (`label = 1`). It covers Turkish (`tur`), Northern Kurdish/Kurmanji
+(`kmr`), Central Kurdish/Sorani (`ckb`), Arabic (`ara`), Persian (`fas`), and
+English (`eng`).
+
+## Dataset composition
+
+| Construction | Mixed | Monolingual | Total |
+|---|---:|---:|---:|
+| Single-call OmniVoice | 500 | 500 | 1,000 |
+| Segment-level OmniVoice | 1,500 | 1,500 | 3,000 |
+| Real-speech concatenation | 1,000 | 1,000 | 2,000 |
+| **Total** | **3,000** | **3,000** | **6,000** |
+
+The split is 80/10/10: 4,800 train, 600 validation, and 600 test clips. Cloned
+voice references, source recordings, and text pools are isolated by split.
+
+## Audio
+
+- 16 kHz mono FLAC
+- 60% clean
+- 20% synthetic colored background noise
+- 10% telephone/radio filtering
+- 10% compression or short-room reverberation
+
+Augmentation is applied after complete clip assembly and has the same
+distribution for both labels.
+
+## Synthetic speech
+
+Synthetic clips were generated with `k2-fsa/OmniVoice`. Twenty distinct
+synthetic reference voices were first created with OmniVoice voice design, then
+used through the voice-cloning interface. Twelve references are exclusive to
+train, four to validation, and four to test. No real person's voice was cloned.
+
+For segment-level mixed clips, 80% use one cloned voice across all languages and
+20% alternate between two cloned voices. Switch patterns are approximately 70%
+A→B, 25% A→B→A, and 5% A→B→A→B. Segment boundaries in `segments` reflect the
+assembled audio before length-preserving full-clip augmentation.
+
+Single-call mixed generation uses language-agnostic conditioning and should be
+treated as the experimental subset described by `construction =
+"single_call_tts"`. It is intended primarily for clip-level evaluation.
+
+## Real speech
+
+Real concatenations use recordings from:
+
+- Google FLEURS (`google/fleurs`), CC BY 4.0
+- KMR-Tatoeba (`aranemini/kmr-tatoeba`), CC BY 4.0
+- LibriSpeech `dev-clean`, CC BY 4.0
+
+Source recording IDs and corpora are retained in each real sample. No source
+recording is used more than three times or shared across dataset splits. Half of
+the real joins are same-corpus and half different-corpus, independently for
+mixed and monolingual labels.
+
+## Fields
+
+- `audio`: viewer-decoded audio from `file_name`
+- `id`: stable sample identifier
+- `label`: `0` for monolingual, `1` for mixed-language
+- `construction`: `single_call_tts`, `segment_tts`, or `real_concatenation`
+- `languages`: unique ISO 639-3 language codes present
+- `language_sequence`: ordered span languages
+- `speaker_condition`: same or different voice condition
+- `segments`: start/end time, language, text, and provenance per span; null for
+  single-call generation
+- `text`: complete input text for single-call generation; null otherwise
+- `audio_condition` and `augmentation_detail`: full-clip audio treatment
+- `reference_voice_ids`, `source_ids`, `source_corpora`: provenance
+- `qc_*`: deterministic file-integrity and signal checks
+
+## Validation and limitations
+
+Every published file is checked for successful decoding, nonzero duration,
+finite samples, sample rate, clipping, annotation consistency, exact class and
+construction counts, split isolation, source reuse, and distribution targets.
+ASR and audio-language-identification scores are intentionally not included.
+Consequently, intended languages—especially in the experimental single-call
+subset—are annotations of the generation request rather than guarantees from an
+independent acoustic recognizer. Human listening is recommended before using
+this pilot as a gold evaluation set.
+
+## Licensing and attribution
+
+The derived dataset is released under CC BY 4.0. Users should also cite the
+upstream FLEURS, KMR-Tatoeba, LibriSpeech, and OmniVoice resources when using the
+corresponding subsets. Text and source identifiers are included to support
+auditing and attribution.
