asr_codeswitched_dataset
Arabic/English Code-Switched ASR Dataset
Audio + transcripts of code-switched Egyptian Arabic and English speech, assembled to
fine-tune ASR for Arab-world lecture content where dialectal Arabic and English technical
vocabulary alternate within sentences.

Dataset Summary
This dataset contains audio recordings and text transcripts of Nepali-English code-switched speech in the context of technical interviews. It is specifically designed to handle the linguistic complexities of Nepali software engineers, developers, and IT professionals who frequently mix English technical terminology (e.g., AWS, S3 lifecycle policies, RAG pipelines, VPC peering) with conversational Nepali grammar.
It is an excellent resource for fine-tuning ASR models… See the full description on the dataset page: https://huggingface.co/datasets/devrahulbanjara/ne-en-codeswitching-asr-technical-interview.khmer-english-codeswitch-tts
Khmer–English Code-Switch Synthetic Speech
8,177 utterances / 15.9 hours of synthetic Khmer–English code-switched speech,
generated with VoxCPM2 from code-switch text
manufactured by confirmed lexical substitution over a Khmer–English parallel corpus.
⚠️ This is synthetic speech, not recordings of people. Every utterance was produced by a
TTS model, and the code-switch sentences were manufactured by word substitution — they are not
transcripts of anything a person said. It is… See the full description on the dataset page: https://huggingface.co/datasets/Panhapich/khmer-english-codeswitch-tts.ljspeech-mimi-codes
LJSpeech — Mimi Codes
Pre-extracted Kyutai Mimi neural-codec tokens for the
LJSpeech corpus — 13,100 English utterances
from a single female speaker reading public-domain audiobook passages (~24 hours).
This dataset contains codes only, not audio. For waveforms, go to the original LJSpeech
release; these codes are designed to be loaded alongside it for training Mimi-based speech
models without paying the ~1 hour of GPU extraction cost.

Code-Switched French–English STT Probe Dataset
Dataset Summary
This dataset contains 10 audio clips of French–English code-switched speech, each designed as a strict probe targeting a distinct acoustic or linguistic failure axis of Kyutai STT (kyutai/stt-1b-en_fr-trfs) — a streaming bilingual speech-to-text model. Probes cover non-native phonology, fast speech rate, word-level and phrase-level code-switching, intrasentential switching, disfluency with switching, and… See the full description on the dataset page: https://huggingface.co/datasets/Atufa/codeswitch-fr-en-kyutai-stt.librispeech-mimi-codes
LibriSpeech — Mimi Codes
Pre-extracted Kyutai Mimi neural-codec tokens for the
LibriSpeech corpus — multi-speaker English audiobook readings
from the LibriVox project.
This dataset contains codes only, not audio. For waveforms, use any of the LibriSpeech
mirrors (e.g. openslr/librispeech_asr);
these codes let you skip the ~hours of GPU extraction needed to train Mimi-based speech models.
