w2v-bert-2.0-nepali-transliterator

• Loss: 0.2366
• Wer: 0.2786

Model Details

• Model Type: Speech-to-Text Transliteration Model
• Language: Nepali (Audio to Romanized Nepali Text)
• Dataset: Labeled Nepali speech dataset with Romanized text pairs
• Base Architecture: wav2vec 2.0 + BERT
• Task: Transliterating spoken Nepali into Romanized Nepali text
• Use Case: Assisting non-Devanagari users in understanding Nepali speech through Romanized output

Direct Use

• Convert Nepali speech into Romanized Nepali text
• Assist non-Devanagari users in understanding spoken Nepali
• Enable voice-based transliteration in chat applications

Out-of-Scope Use

• Not for General Nepali Speech-to-Text – This model specifically transliterates into Roman Nepali instead of generating text in Devanagari script.
• Not optimized for noisy environments – Performance may drop in low-quality or multi-speaker recordings.
• May not handle code-switching well – If Nepali is mixed with English or other languages, accuracy might decrease.
