In this section, we’ll go through
some of the most common audio classification tasks and suggest appropriate pre-trained models for each. Using the <code>pipeline()</code>
class, switching between models and tasks is straightforward - once you know how to use <code>pipeline()</code> for one model, you’ll
be able to use it for any model on the Hub no code changes! This makes experimenting with the <code>pipeline()</code> class extremely
fast, allowing you to quickly select the best pre-trained model for your needs.`,Xe,U,vs=`Before we jump into the various audio classification problems, let’s quickly recap the transformer architectures typically
used. The standard audio classification architecture is motivated by the nature of the task; we want to transform a sequence
of audio inputs (i.e. our input audio array) into a single class label prediction. Encoder-only models first map the input
audio sequence into a sequence of hidden-state representations by passing the inputs through a transformer block. The
sequence of hidden-state representations is then mapped to a class label output by taking the mean over the hidden-states,
and passing the resulting vector through a linear classification layer. Hence, there is a preference for <em>encoder-only</em>
models for audio classification.`,Oe,J,Us=`Decoder-only models introduce unnecessary complexity to the task, since they assume that the outputs can also be a <em>sequence</em>
of predictions (rather than a single class label prediction), and so generate multiple outputs. Therefore, they have slower
inference speed and tend not to be used. Encoder-decoder models are largely omitted for the same reason. These architecture
choices are analogous to those in NLP, where encoder-only models such as <a href="https://huggingface.co/blog/bert-101" rel="nofollow">BERT</a>
are favoured for sequence classification tasks, and decoder-only models such as GPT reserved for sequence generation tasks.`,Ke,C,Js=`Now that we’ve recapped the standard transformer architecture for audio classification, let’s jump into the different
subsets of audio classification and cover the most popular models!`,et,$,tt,k,Cs=`At the time of writing, the latest updates required for audio classification pipeline are only on the <code>main</code> version of

recognition model.`,bt,R,qs=`The audio classification model is much smaller and lighter than the speech recognition model, often only several millions
of parameters compared to several hundred millions for speech recognition. Thus, it can be run continuously on your device

possible classes. This poses a barrier to using pre-trained models for audio classification, since the label set of the
pre-trained model must match that of the downstream task. For the previous example of LID, the model must predict one of
the 102 langauge classes on which it was trained. If the downstream task actually requires 110 languages, the model would
not be able to predict 8 of the 110 languages, and so would require re-training to achieve full coverage. This limits the
effectiveness of transfer learning for audio classification tasks.`,es,ve,oa=`Zero-shot audio classification is a method for taking a pre-trained audio classification model trained on a set of labelled

CLAP is a transformer-based model that takes both audio and text as inputs, and computes the <em>similarity</em> between the two.
If we pass a text input that strongly correlates with an audio input, we’ll get a high similarity score. Conversely, passing
a text input that is completely unrelated to the audio input will return a low similarity.`,ss,Je,ra=`We can use this similarity prediction for zero-shot audio classification by passing one audio input to the model and
multiple candidate labels. The model will return a similarity score for each of the candidate labels, and we can pick the
one that has the highest score as our prediction.`,as,Ce,ha=`Let’s take an example where we use one audio input from the <a href="https://huggingface.co/datasets/ashraq/esc50" rel="nofollow">Environmental Speech Challenge (ESC)</a>
dataset:`,ls,$e,ns,ke,ca=`We then define our candidate labels, which form the set of possible classification labels. The model will return a
classification probability for each of the labels we define. This means we need to know <em>a-priori</em> the set of possible
labels in our classification problem, such that the correct label is contained within the set and is thus assigned a
valid probability score. Note that we can either pass the full set of labels to the model, or a hand-selected subset
that we believe contains the correct label. Passing the full set of labels is going to be more exhaustive, but comes
at the expense of lower classification accuracy since the classification space is larger (provided the correct label is
our chosen subset of labels):`,is,Ie,os,Ne,da="We can run both through the model to find the candidate label that is <em>most similar</em> to the audio input:",ps,We,rs,Le,ua="<strong>Output:</strong>",hs,He,cs,_e,ma=`Alright! The model seems pretty confident we have the sound of a dog - it predicts it with 99.96% probability, so we’ll

volume too high or else you might get a jump!):`,ds,qe,us,Ze,fa=`Perfect! We have the sound of a dog barking 🐕, which aligns with the model’s prediction. Have a play with different audio
samples and different candidate labels - can you define a set of labels that give good generalisation across the ESC
dataset? Hint: think about where you could find information on the possible sounds in ESC and construct your labels accordingly!`,ms,ze,ya=`You might be wondering why we don’t use the zero-shot audio classification pipeline for <strong>all</strong> audio classification tasks?
It seems as though we can make predictions for any audio classification problem by defining appropriate class labels <em>a-priori</em>,
thus bypassing the constraint that our classification task needs to match the labels that the model was pre-trained on.
This comes down to the nature of the CLAP model used in the zero-shot pipeline: CLAP is pre-trained on <em>generic</em> audio
classification data, similar to the environmental sounds in the ESC dataset, rather than specifically speech data, like
we had in the LID task. If you gave it speech in English and speech in Spanish, CLAP would know that both examples were
speech data 🗣️ But it wouldn’t be able to differentiate between the languages in the same way a dedicated LID model is
able to.`,fs,Qe,ys,Se,ga=`We’ve covered a number of different audio classification tasks and presented the most relevant datasets and models that
