我有几个文件，如Train.js和Result.js。我如何使导出voiceData从Train.js到Result.js？文件如下：
Train.js

const Train = () => {
  const [user] = useAuth()
  let [started, setStarted] = useState(false);
  let [results, setResults] = useState([]);
  const [voiceData, setVoiceData] = useState([]);
  
  const navigation = useNavigation()
  const toResult = () => {
    navigation.navigate('Result')

}

Result.js:

return (
    <View style={styles.container}>
      <Text>{voiceData}</Text>
      <View>
