Code-Switching Dataset for Tokenizer Robustness Analysis
Dataset Description
This dataset is designed for tokenizer robustness testing in multilingual and code-switching contexts. It contains identical content expressed across 16 different language variants, including pure English and 15 English-X code-switching pairs, allowing researchers to isolate tokenization effects from semantic differences when evaluating language models.
Purpose

This dataset is derived from espnet/yodas, more details can be found here: https://huggingface.co/datasets/espnet/yodas
This is a subset of the zh000 subset of espnet/yodas dataset, which selects videos with Mandarin-English code-switching phenomenon.
Note that code-switching is only gauranteed per video rather than per utterance. Therefore, not every utterance in the dataset contains code-switching.

1043 held-out cross-script utterance pairs from 8 ElevenLabs Western Multilingual voices. Used to evaluate generalisation of speaker encoders trained on Praxel/codeswitch-pairs-lase.
Each row is one synthesized utterance with metadata; pairs are reconstructed at evaluation time by joining on voice_id (same voice, different script = cross-script pair).

Synthetic English Code-Switching Evaluation Set
This dataset contains synthetic long-form English code-switching audio samples built from ML-SUPERB hybrid data.
Each mixed sample combines English with exactly one additional language. Durations are randomly drawn between 5 and 15 minutes, and each sample contains one or two code switches. The random seed is stored per row.
Each selected utterance chunk is RMS-normalized to -20.0 dBFS before concatenation, with peak limiting at 0.99.… See the full description on the dataset page: https://huggingface.co/datasets/BrunoHays/english-x-code-switching.naturalnessenglish-en-x-code-switching-main-lang

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).

Chichewa-English Code-Switched Speech Dataset
Dataset Description
A speech dataset containing 247 audio recordings of Chichewa-English code-switched phrases. Code-switching — the practice of alternating between two or more languages within a single conversation — is extremely common in Malawi and across multilingual African communities. This dataset captures that natural linguistic behavior in spoken form.
Purpose
