c# - 谷歌语音转文本 API : Enable Word Confidence Not Found

Question

我无法将单词级别的置信度添加到我的替代结果中，有人可以帮忙吗？

我尝试阅读以下页面: https://cloud.google.com/speech-to-text/docs/word-confidence#speech-word-level-confidence-python 但我无法更改我的代码以检索单词级别的置信度

Encoding = AudioEncoding.Linear16,
SampleRateHertz = 44100,
LanguageCode = LanguageCodes.English.SouthAfrica,
EnableWordTimeOffsets = true,
EnableAutomaticPunctuation = true,
UseEnhanced = true,
EnableWordConfidence = true; 

foreach (var result in response.Results){

    foreach (var alternative in result.Alternatives){

        returnedText += alternative.Transcript + " ";

        foreach (var item in alternative.Words){
            var startTime = item.StartTime;
            var endTime = item.EndTime;
            var confidence = item.Confidence; 
        }

    }

}

根据 documentation page，单词置信度是一项预发布功能因此它仅适用于特定的 API 用户组。尚未对所有人开放。
