+# useSpeechSynthesis
+
+A hook that provides an interface for using the [Web_Speech_API](https://developer.mozilla.org/en-US/docs/Web/API/Web_Speech_API) to
+recognize and transcribe speech in a user's browser.
+
+### Why? 💡
+
+- Abstracts the implementation details of the Web Speech API into a single reusable function.
+
+### Basic Usage:
+
+```jsx harmony
+import { Button, Space, Tag, Typography, Input } from 'antd';
+import useSpeechRecognition from 'beautiful-react-hooks/useSpeechRecognition';
+
+const SpeechSynthesisDemo = () => {
+  const [name, setName] = React.useState('Antonio');
+  const { startRecording, transcript, stopRecording, isRecording, isSupported } = useSpeechRecognition();
+
+  return (
+    <DisplayDemo title="useSpeechSynthesis">
+      <Space direction="vertical">
+        <Typography.Paragraph>
+          Supported: <Tag color={isSupported ? 'green' : 'red'}>{isSupported ? 'Yes' : 'No'}</Tag>
+        </Typography.Paragraph>
+        <Button onClick={!isRecording ? startRecording : stopRecording} type="primary">
+          {isRecording ? 'Stop' : 'Start'} recording
+        </Button>
+        <Typography.Paragraph>
+          {transcript}
+        </Typography.Paragraph>
+      </Space>
+    </DisplayDemo>
+  );
+};
