audio applications. As you’ve experienced, building more involved audio tools is fully within reach by using the
foundational skills you’ve acquired in this course.</p> <p data-svelte-h="svelte-1vndh8y">The hands-on exercise takes one of the applications covered in this Unit, and extends it with a few multilingual
tweaks 🌍 Your objective is to take the <a href="https://huggingface.co/spaces/course-demos/speech-to-speech-translation" rel="nofollow">cascaded speech-to-speech translation Gradio demo</a>
from the first section in this Unit, and update it to translate to any <strong>non-English</strong> language. That is to say, the
demo should take speech in language X, and translate it to speech in language Y, where the target language Y is not
English. You should start by <a href="https://huggingface.co/spaces/course-demos/speech-to-speech-translation?duplicate=true" rel="nofollow">duplicating</a>
the template under your Hugging Face namespace. There’s no requirement to use a GPU accelerator device - the free CPU
tier works just fine 🤗 However, you should ensure that the visibility of your demo is set to <strong>public</strong>. This is required
such that your demo is accessible to us and can thus be checked for correctness.</p> <p data-svelte-h="svelte-1xc515h">Tips for updating the speech translation function to perform multilingual speech translation are provided in the
section on <a href="speech-to-speech">speech-to-speech translation</a>. By following these instructions, you should be able
to update the demo to translate from speech in language X to text in language Y, which is half of the task!</p> <p data-svelte-h="svelte-e3qygk">To synthesise from text in language Y to speech in language Y, where Y is a multilingual language, you will need
to use a multilingual TTS checkpoint. For this, you can either use the SpeechT5 TTS checkpoint that you fine-tuned
in the previous hands-on exercise, or a pre-trained multilingual TTS checkpoint. There are two options for pre-trained
checkpoints, either the checkpoint <a href="https://huggingface.co/sanchit-gandhi/speecht5_tts_vox_nl" rel="nofollow">sanchit-gandhi/speecht5_tts_vox_nl</a>,
which is a SpeechT5 checkpoint fine-tuned on the Dutch split of the <a href="https://huggingface.co/datasets/facebook/voxpopuli" rel="nofollow">VoxPopuli</a>
dataset, or an MMS TTS checkpoint (see section on <a href="../chapter6/pre-trained_models">pretrained models for TTS</a>).</p>  <div class="course-tip  bg-gradient-to-br dark:bg-gradient-to-r before:border-green-500 dark:before:border-green-800 from-green-50 dark:from-gray-900 to-white dark:to-gray-950 border border-green-50 text-green-700 dark:text-gray-400">In our experience experimenting with the Dutch language, using an MMS TTS checkpoint results in better performance than a
    fine-tuned SpeechT5 one, but you might find that your fine-tuned TTS checkpoint is preferable in your language.
    If you decide to use an MMS TTS checkpoint, you will need to update the <a href="https://huggingface.co/spaces/course-demos/speech-to-speech-translation/blob/a03175878f522df7445290d5508bfb5c5178f787/requirements.txt#L2" data-svelte-h="svelte-l0vtp8">requirements.txt</a>
    file of your demo to install <code data-svelte-h="svelte-olzpwg">transformers</code> from the PR branch:
    <p data-svelte-h="svelte-1oo2kle"><code>git+https://github.com/hollance/transformers.git@6900e8ba6532162a8613d2270ec2286c3f58f57b</code></p></div> <p data-svelte-h="svelte-r6bgbz">Your demo should take as input an audio file, and return as output another audio file, matching the signature of the
<a href="https://huggingface.co/spaces/course-demos/speech-to-speech-translation/blob/3946ba6705a6632a63de8672ac52a482ab74b3fc/app.py#L35" rel="nofollow"><code>speech_to_speech_translation</code></a>
function in the template demo. Therefore, we recommend that you leave the main function <code>speech_to_speech_translation</code>
as is, and only update the <a href="https://huggingface.co/spaces/course-demos/speech-to-speech-translation/blob/a03175878f522df7445290d5508bfb5c5178f787/app.py#L24" rel="nofollow"><code>translate</code></a>

functions as required.</p> <p data-svelte-h="svelte-xkt7xj">Once you have built your demo as a Gradio demo on the Hugging Face Hub, you can submit it for assessment. Head to the
Space <a href="https://huggingface.co/spaces/huggingface-course/audio-course-u7-assessment" rel="nofollow">audio-course-u7-assessment</a> and
provide the repository id of your demo when prompted. This Space will check that your demo has been built correctly by
sending a sample audio file to your demo and checking that the returned audio file is indeed non-English. If your demo
works correctly, you’ll get a green tick next to your name on the overall <a href="https://huggingface.co/spaces/MariaK/Check-my-progress-Audio-Course" rel="nofollow">progress space</a> ✅</p> <a class="!text-gray-400 !no-underline text-sm flex items-center not-prose mt-4" href="https://github.com/huggingface/audio-transformers-course/blob/main/chapters/en/chapter7/hands_on.mdx" target="_blank"><span data-svelte-h="svelte-1kd6by1">&lt;</span> <span data-svelte-h="svelte-x0xyl0">&gt;</span> <span data-svelte-h="svelte-1dajgef"><span class="underline ml-1.5">Update</span> on GitHub</span></a>  <p></p>
