Griot Nano 1 Multilingual KenLM

This is the multilingual 3-gram KenLM language model for Qlerqly/griot-nano-1. It covers Akan, Dagbani, Ewe, Ghanaian English, and Ga using the same normalized transcript domain as the Griot Nano 1 acoustic model.

Recommended decoding configuration

For best contextual accuracy, we recommend KenLM-assisted CTC beam search with Griot Nano 1. It improves the decoder's preference for plausible character and word sequences, particularly around ambiguous acoustics and word boundaries.

KenLM is a compact n-gram model rather than a second neural network. This keeps memory and compute overhead low relative to neural language-model rescoring. Greedy CTC remains the lowest-latency option.

Suggested starting settings:

• Beam width: 25
• LM weight (alpha): 0.5
• Word insertion bonus (beta): 1.0

These are starting points rather than universal optima; tune them on a held-out set for your target language and domain.
