nepali-cs-asr
Nepali–English Code-Switched ASR
A ~59-hour corpus of spontaneous Nepali–English code-switched speech clipped from publicly available STEM and CS lecture videos on YouTube. The dataset targets ASR model training and evaluation for code-switched (CS) Nepali–English speech — a variety commonly used in Nepali higher education and online tutoring, where teachers fluidly mix Nepali grammar with English technical vocabulary.

Nepali two-speaker conversation chunks
~6680.8 h of Nepali speech at 48 kHz. Two speakers per clip, ~5 minute diarized chunks.
A backup, not a release: the transcripts are machine-generated, and none of this
audio passed the quality gate that produced our training corpus.
Derived from third-party audio whose rights holders did not grant redistribution. The hour count is language-dominant, not monolingual: a chunk labelled Nepali can carry substantial English or Hindi. lang_sec… See the full description on the dataset page: https://huggingface.co/datasets/milanakdj/nepali-audio-reserve-r6.nepali-tts-synthetic-v2
Nepali TTS Synthetic v2
383,298 synthetic Nepali (ne) speech/text pairs, 24 kHz mono 16-bit WAV embedded
as-is (no re-encode, no resampling).
Generated by the synthetic_pipeline in milanakdj/TTS_training: Edge TTS
synthesis → optional voice conversion against a pool of 600 real multi-speaker
reference clips → ASR-based QC gate on character error rate.

Nepali Speech-to-Text Dataset
This repository contains a dataset for Automatic Speech Recognition (ASR) in the Nepali language. The dataset is designed for supervised learning tasks and includes audio files along with their corresponding transcriptions. The audio samples have been collected from various open-source platforms and other publicly available sources on the internet.
Each audio file has an average length of 15 seconds and has been converted into a consistent WAV format… See the full description on the dataset page: https://huggingface.co/datasets/pujanpaudel/nepali_speech_to_text.no-filter-raw-NepaliParliamentDSv2seke-nepali-dataset
🏔️ Seke (SKJ) Language Dataset
Endangered Language Alliance × Internet Archive
Seke (skj) is a critically endangered Sino-Tibetan language spoken by approximately 700 people
in the five villages of Upper Mustang district, Nepal, and in diaspora communities in New York City.
This dataset represents one of the most complete public audio corpora of Seke ever assembled.
Dataset created by Anil Tamang (himalaya-ai).
