Code-Switching ASR
Code-switching ASR is a speech dataset of code-switching between English and medium to low resource languages. Samples include en-sw, en-pcm, en-yo, and en-tl but we can deliver any of the languages listed here: https://huggingface.co/datasets/liva-ai/yapdo-convo (the hours have yet to be updated as of 07/14/2026 as we have much higher volume now - and we can easily collect more… See the full description on the dataset page: https://huggingface.co/datasets/liva-ai/code-switching-asr.asr_codeswitched_dataset
Arabic/English Code-Switched ASR Dataset
Audio + transcripts of code-switched Egyptian Arabic and English speech, assembled to

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.kazakh-codeswitch-asr
Kazakh Code-Switching ASR Benchmark
A benchmark for evaluating ASR systems on natural Kazakh speech that
code-switches with Russian — the everyday Kazakh–Russian mixing found in
stand-up, interviews and vlogs, not scripted read speech. This is, to our
knowledge, the first speech/ASR resource targeting the Kazakh–Russian
code-switching pair (existing Kazakh–Russian NLP resources are text-only).
Code, scoring harness and full analysis:… See the full description on the dataset page: https://huggingface.co/datasets/Tim2190/kazakh-codeswitch-asr.id-en-codeswitch-dataset-alternative
Indonesian–English Code-Switching Synthetic Speech Dataset
Synthetic speech generated for the undergraduate final project "Handling
Code-Switching in Automatic Speech Recognition for Low-Resource Language
Pairs: An Indonesian–English Case Study", School of Electrical Engineering
and Informatics, Institut Teknologi Bandung.
This dataset contains synthetic audio produced from the Indonesian–English
code-switching text corpora released in the companion repository below. It
was used… See the full description on the dataset page: https://huggingface.co/datasets/shulhaaja/id-en-codeswitch-dataset-alternative.vocal-money-codeswitch-asr-benchmark
Vocal Money — Yoruba–English Code-Switched ASR Benchmark
A 210-clip evaluation subset used to benchmark five speech recognition systems on naturally
code-switched Yoruba–English speech, together with the reference transcriptions and the output of
every system on every clip, so that the published results can be recomputed or contradicted.
Produced for the MLC (Africa) × Intron Agentic Voice AI Challenge, Deep Learning Indaba 2026.

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.codeswitch-fr-en-kyutai-stt
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.code-switch_chunks

Kare — Code-Switching Illustrative Samples
Eight short audio clips demonstrating the English/Yoruba/Hausa/Igbo/Pidgin
code-switching that Kare, a voice-first
AI health assistant for Nigeria, is built to understand — submitted as part
of Kare's entry to the Sahara CodeSwitch Africa Challenge.
What this is — and isn't
Is: eight original sentences, written by the Kare team specifically
for this demonstration, mixing everyday Yoruba / Hausa / Igbo / Nigerian
Pidgin… See the full description on the dataset page: https://huggingface.co/datasets/vikkyblacq/kare-codeswitch-samples.switchboard-tierb-codeswitch
SwitchBoard Tier B — African code-switched speech
87 consented utterances of intra-sentential code-switching — Nigerian Pidgin,
Yorùbá, Hausa and Kiswahili each mixed with English inside a single sentence —
recorded from 8 bilingual volunteers at the Deep Learning Indaba 2026, Lagos.
Collected for the MLC (Africa) × Intron Agentic Voice AI Challenge as an
evaluation set for telco/fintech voice agents. 8.75 minutes total.
What this is for
Measuring whether a speech… See the full description on the dataset page: https://huggingface.co/datasets/mosesdaudu/switchboard-tierb-codeswitch.codeswitching
