| This is an example script for training (SFT/PEFT) multi-modal speech-to-text LLM using NeMo. | |
| All SpeechLMs that has the three componnets (audio encoder, modality adapter and LLM) are supported. | |
| Some example models are: | |
| - SALM (https://arxiv.org/abs/2310.09424) | |
| - VoiceTextBlender (https://arxiv.org/abs/2410.17485) | |
