+# Khmer ASR Cultural Dataset
+
+727.94 hours of manually curated speech-text pairs by native speakers in the Khmer language about Cambodian cultural topics. On average, each recording is 8 seconds. Speaker metadata (gender, age group, and origin city) is provided.
+
+- Language: Khmer (khm).
+- Source(s): Native speakers from Cambodia (5 females, 7 males). The utterances were manually generated based on topics and subtopics listed in metadata.
+- Domain(s): Cultural domain, with a total of 61 topics and 1,749 subtopics.
+- Size: 495.9GB data instances
+- WAV file names are formatted as: `{speaker_id}_khm_{sentence_id}.wav`.
+
+## Sample
+
+The first row of our metadata.csv:
+
+| Topic | Subtopic | Speaker ID | Paragraph ID | Sentence ID | Sentences |

+**Khmer ASR Cultural Dataset** is also available on [Mozilla Data Collective](https://datacollective.mozillafoundation.org/datasets/cml9h5vgc01bxmn075sjeftek).
+
+## Use cases
+
+### Automatic speech recognition (ASR)
+
+Off-the-shelf state-of-the-art multilingual automatic speech recognition pre-trained models (e.g., [OpenAI's Whisper](https://huggingface.co/collections/openai/whisper-release)) cannot transcribe Khmer well. Even with further fine-tuning, the error rate (lower is better, 0% means no errors/perfect) for Khmer ASR is far from usable [(Lovenia, 2025)](https://arxiv.org/pdf/2406.10118). See the `khm` column in Figure 3 below.
+
+![image](https://cdn-uploads.huggingface.co/production/uploads/616cd2e040e2f69baa1c7af2/CbVshGEs23FqaXROuKn25.png)
+
+To have a good automatic speech recognition (ASR) model for Khmer, you will require a large amount of speech-text pairs in Khmer. However, before **Khmer ASR Cultural Dataset** is available, there was only one Khmer speech-text dataset: [OpenSLR 42](https://openslr.org/42/) with 3.97 hours of speech-text pairs (male only).
+
+Our preliminary experiment shows that even only by adding 650 speech-text pairs from DDD's dataset to the training data, we can decrease the Whisper models' CER by around 0.46%-0.74% compared to only using OpenSLR 42 in the training data. Now the Whisper Large V2's performance in Khmer drops to only 8.11% CER. With more speech-text pairs collected by DDD, ASR models' performance in Khmer will definitely be able to transcribe Khmer audios with even less errors.
+
+### Other potential use cases
+
+**Khmer ASR Cultural Dataset** can also be used to train models on Khmer text-to-speech (TTS), language modeling, topic modeling, and next sentence prediction.
