In several natural language processing applications, text-based big language models have shown impressive and even human-level performance. In the mean time, an LLM training paradigm generally known as instruction tuning—during which data is arranged as pairs of user instruction and reference response—has evolved that permits LLMs to comply with unrestricted user commands. Increasingly, researchers are excited by equipping LLMs with multimodal sensory skills. Current research focuses on linking LLMs to the encoder of yet another input type—resembling a picture, silent video, audio event, or speech—or to the encoders of many input kinds together. 

To align the encoder output spaces with the LLM input space—which is usually taught through cross-modal pre-training and instruction tuning—one can utilize a connection module and LLM adaptors. The speech audio language music open neural network that’s proposed on this study is a single audio-text multimodal LLM that may recognize and comprehend speech, audio events, and music—the three foremost categories of sounds. SALMONN employs a dual encoder framework, comprising a BEATs audio encoder and a speech encoder from the Whisper speech model, to enhance performance on each speech and nonspeech audio applications. 

To further enhance Vicuna’s performance, the low-rank adaption strategy is utilized as a cross-modal adaptor to match the augmented input space with the output space. The cross-modal pre-training and instruction tuning phases of the window-level Q-Former and LoRA employ many speech, audio, and music challenges. The resultant multimodal LLMs show little to no cross-modal emergent skills and could be restricted to the particular sorts of tasks utilized in instruction tuning, specifically audio captioning and voice recognition, which they term the duty over-fitting problem. The power to execute cross-modal tasks that will not be noticed during training is referred to on this study as cross-modal emergent skills. These abilities are mainly the emergent capabilities of LLMs which are lost during instruction tailoring. 

With a purpose to mitigate the numerous catastrophic forgetting of the training tasks, they suggest adding a further few-shot activation tuning stage to SALMONN’s repertoire. SALMONN’s cognitive hearing abilities are assessed using a wide range of speech, auditory events, and music standards. There are three levels to the tasks. The primary two levels test untrained activities, while the primary level benchmarks eight tasks which are taught in instruction tuning, including audio captioning, translation, and voice recognition. Five speech-based natural language processing (NLP) tasks, including slot filling and translation to untrained languages, are included within the second level. These tasks need multilingual and high-quality alignments between voice and text tokens. 

Comprehending non-speech auditory information is vital for the last set of activities, resembling audio-based narrative and speech audio co-reasoning. The outcomes of the experiments exhibit that SALMONN can complete all of those tasks and perform competitively on industry benchmarks when used as a single model. This implies that it is feasible to create artificial intelligence that’s able to “hearing” and comprehending a wide range of audio inputs, including speech, audio events, and music. 

This paper’s primary contribution could also be summed up as follows. 

• To the perfect of their knowledge, researchers from Tsinghua University and ByteDance offer SALMONN, the primary multimodal LLM that may recognize and comprehend general audio inputs including voice, audio events, and music. 

• By various the LoRA scaling factor, they investigate the existence of cross-modal emergent skills. They then suggest a low-cost activation tuning technique as a further training step that may activate these abilities and reduce catastrophic forgetting to tasks encountered during training. 

• They supply two recent tasks, audio-based storytelling and spoken audio co-reasoning, and assess SALMONN on a wide range of tasks that represent a variety of general hearing skills.
