我最近才开始使用 R 和软件包googleLanguageR- 太棒了！

我有超过 400 个 .flac 文件（每个大约 20 秒），我想使用 .flac 将它们转换为文本gl_speech。

我写了以下循环：

for (i in files) {
  possibleError <- tryCatch({ 
    participantid = str_sub(i, 1, 3)
    patha = paste(path_in, i, sep='')
    result <- gl_speech(patha, 
                     sampleRateHertz = 44100L,
                     customConfig = my_config)
    transcript2 <- subset(result$transcript, select=-c(languageCode, channelTag))
    transcriptid <- cbind(participantid, transcript2)
    write_delim(as.data.frame(transcriptid),file.path(path_in,paste0(participantid,'_text.csv')))
  }, 
    error = function(e) e)
  
    if(inherits(possibleError, "error"))  next 
  
    }

为了完整起见， my_config 是：

my_config <- list(audioChannelCount = 2, 
                  encoding = "FLAC",
                   maxAlternatives = 30,
                  languageCode = "en-US",
                  model = "video"
)

我一次为 2、5 或 10 个文件执行此操作。其中有几个返回错误。错误信息是：

  <p><b>408.</b> <ins>That’s an error.</ins>

但是，当我稍后单独运行返回错误的文件时，gl_speech不会返回此错误。

是否有不同的方法来循环多个文件以避免尽可能多的错误？
