💻 This demo showcases a general-purpose speech recognition model called Whisper. It is trained on a large dataset of diverse audio and supports multilingual speech recognition, speech translation, and language identification tasks.<br><br>
<br>
⚙️ Components of the tool:<br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp; - Real-time multilingual speech recognition<br>
&nbsp;&nbsp;&nbsp;&nbsp; - Language identification<br>
&nbsp;&nbsp;&nbsp;&nbsp; - Sentiment analysis of the transcriptions<br>
<br>
🎯 The sentiment analysis results are provided as a dictionary with different emotions and their corresponding scores.<br>
<br>

😃 The sentiment analysis results are displayed with emojis representing the corresponding sentiment.<br>
<br>

✅ The higher the score for a specific emotion, the stronger the presence of that emotion in the transcribed text.<br>
<br>

❓ Use the microphone for real-time speech recognition.<br>
<br>

⚡️ The model will transcribe the audio and perform sentiment analysis on the transcribed text.<br>
