Speech GO SDK don't support Continues Detect Language

[ZenoRewn]

Speech GO SDK don't support Continues Detect Language. Base on SDK 1.44.0

If I speak English first then speak Chinese in my test, GO SDK will recognize it as English at all.
Base on Issues' research, I can you can add two line hard code to fixed it.

	**const SpeechServiceConnectionLanguageIdMode common.PropertyID = 3205**
	speechConfig.SetProperty(SpeechServiceConnectionLanguageIdMode, "Continuous")

Can you help fixed it? and make GO SDK directly support SpeechServiceConnectionLanguageIdMode as "Continuous".
It's only missing a PropertyID setting.

No PropertyID setting screenshot:

With PropertyID setting screenshot:

Sample Code as below:

package main

import (
	"bufio"
	"fmt"
	"log"
	"os"
	"time"

	"github.com/Microsoft/cognitive-services-speech-sdk-go/common"
	"github.com/Microsoft/cognitive-services-speech-sdk-go/speech"
)

func continuousLanguageDetection() {
	speechKey := os.Getenv("ASIA_SPEECH_KEY")
	speechRegion := os.Getenv("ASIA_SPEECH_REGION")

	if speechKey == "" || speechRegion == "" {
		log.Fatal("错误: 请设置 ASIA_SPEECH_KEY 和 ASIA_SPEECH_REGION 环境变量。")
	}

	speechConfig, err := speech.NewSpeechConfigFromSubscription(speechKey, speechRegion)
	if err != nil {
		log.Fatalf("创建语音配置失败: %v", err)
	}
	defer speechConfig.Close()

	speechConfig.SetOutputFormat(common.Detailed)

	const SpeechServiceConnectionLanguageIdMode common.PropertyID = 3205
	speechConfig.SetProperty(SpeechServiceConnectionLanguageIdMode, "Continuous")

	candidateLanguages := []string{"zh-CN", "en-US"}
	autoDetectConfig, err := speech.NewAutoDetectSourceLanguageConfigFromLanguages(candidateLanguages)
	if err != nil {
		log.Fatalf("创建自动语言检测配置失败: %v", err)
	}
	defer autoDetectConfig.Close()

	var audioConfig *audio.AudioConfig
	if len(os.Args) > 1 {
		audioConfig, err = audio.NewAudioConfigFromWavFileInput(os.Args[1])
		if err != nil {
			log.Fatalf("创建音频文件配置失败: %s", err)
		}
	} else {
		audioConfig, err = audio.NewAudioConfigFromDefaultMicrophoneInput()
		if err != nil {
			log.Fatalf("创建麦克风配置失败: %v", err)
		}
	}
	defer audioConfig.Close()

	speechRecognizer, err := speech.NewSpeechRecognizerFomAutoDetectSourceLangConfig(speechConfig, autoDetectConfig, audioConfig)
	if err != nil {
		log.Fatalf("创建语音识别器失败: %v", err)
	}
	defer speechRecognizer.Close()

	speechRecognizer.Recognized(func(event speech.SpeechRecognitionEventArgs) {
		defer event.Close()
		if event.Result.Reason == common.RecognizedSpeech {
			fmt.Printf("✅ [%s] %s\n",
				time.Now().Format("15:04:05"), event.Result.Text)
		}
	})

	err = <-speechRecognizer.StartContinuousRecognitionAsync()
	if err != nil {
		log.Fatalf("启动持续识别失败: %v", err)
	}

	fmt.Println("识别已启动，按 Enter 键停止...")
	bufio.NewReader(os.Stdin).ReadBytes('\n')

	err = <-speechRecognizer.StopContinuousRecognitionAsync()
	if err != nil {
		log.Printf("停止识别时出错: %v", err)
	}
}

func main() {
	continuousLanguageDetection()
}
