SEW-D by ASAPP Research
The base model pretrained on 16kHz sampled speech audio. When using the model make sure that your speech input is also sampled at 16Khz. Note that this model should be fine-tuned on a downstream task, like Automatic Speech Recognition, Speaker Identification, Intent Classification, Emotion Recognition, etc…

Abstract
This paper is a study of performance-efficiency trade-offs in pre-trained models for automatic speech recognition (ASR). We focus on wav2vec 2.0, and formalize several architecture designs that influence both the model performance and its efficiency. Putting together all our observations, we introduce SEW (Squeezed and Efficient Wav2vec), a pre-trained model architecture with significant improvements along both performance and efficiency dimensions across a variety of training setups. For example, under the 100h-960h semi-supervised setup on LibriSpeech, SEW achieves a 1.9x inference speedup compared to wav2vec 2.0, with a 13.5% relative reduction in word error rate. With a similar inference time, SEW reduces word error rate by 25-50% across different model sizes.

Usage
See this blog for more information on how to fine-tune the model. Note that the class Wav2Vec2ForCTC has to be replaced by SEWDForCTC.

以 Meta 开源 LLaMA(直译为「大羊驼」)系列模型为起点,斯坦福大学等机构的研究人员先后在其上进行「二创」,开源了基于 LLaMA 的 Alpaca(羊驼)、Alpaca-Lora、Luotuo(骆驼)等轻量级类 ChatGPT 模型,大大降低了这类模型的研究、应用门槛,训练、推理成本一再降低。由于「二创」过于丰富,生物学羊驼属的英文单词都快不够用了,但富有创意的研究者似乎总能给他们的模型找到新名字。近日,来自加州大学伯克利分校、卡内基梅隆大学、斯坦福大学、加州大学圣迭戈分校的研究者们又提出了一个新的模型 ——Vicuna(小羊驼)。这个模型也是基于 LLaMA,不过用到的是 13B 参数量的版本(作者表示,初步人工评测显示 13B 版本比 7B 版本模型要好不少,不过这不是一个严谨的结论)。
