MS Video Indexer Transcript Issue - Good quality at the beginning of the video, but poor quality from a certain point

I'm trying to use MS Video Indexer ( to generate transcript/subtitle in Brazilian portuguese for a video set, but I'm getting poor quality transcript from a certain point of video. I mean... It starts by transcribing well in the first few minutes of the video, but from a certain point the generated transcript becomes meaningless or generates no transcription. IMPORTANT: the media that I'm testing has good audio quality. I already tried both to set the language of media as 'pt-BR' or to use the language autodetect function. Both produced the same bad result.
