+description = """
+The <b>SpeechT5</b> model is pre-trained on text as well as speech inputs, with targets that are also a mix of text and speech.
+By pre-training on text and speech at the same time, it learns unified representations for both, resulting in improved modeling capabilities.
+
+SpeechT5 can be fine-tuned for different speech tasks. This space demonstrates the <b>speech-to-text</b>
+or automatic speech recognition (ASR) checkpoint for the English language.
+
+See also the <a href="https://huggingface.co/spaces/Matthijs/speecht5-tts-demo">text-to-speech (TTS) demo</a>
+and the <a href="https://huggingface.co/spaces/Matthijs/speecht5-vc-demo">voice conversion demo</a>.
+
+<b>How to use:</b> Upload an audio file or record using the microphone. The audio is converted to mono and resampled to 16 kHz before
+being passed into the model. The output is the text transcription of the audio. SpeechT5 uses a simple character-based tokenizer, with no
+additional language model on top, so the output won't have punctuation or capitalization and may contain the occasional spelling error.
