Google Professional Machine Learning Engineer Exam - Topic 5 Question 86 Discussion

Actual exam question for Google's Professional Machine Learning Engineer exam

Question #: 86
Topic #: 5

[All Professional Machine Learning Engineer Questions]

You work at an organization that maintains a cloud-based communication platform that integrates conventional chat, voice, and video conferencing into one platform. The audio recordings are stored in Cloud Storage. All recordings have an 8 kHz sample rate and are more than one minute long. You need to implement a new feature in the platform that will automatically transcribe voice call recordings into a text for future applications, such as call summarization and sentiment analysis. How should you implement the voice call transcription feature following Google-recommended best practices?

AUse the original audio sampling rate, and transcribe the audio by using the Speech-to-Text API with synchronous recognition.

BUse the original audio sampling rate, and transcribe the audio by using the Speech-to-Text API with asynchronous recognition.

CUpsample the audio recordings to 16 kHz. and transcribe the audio by using the Speech-to-Text API with synchronous recognition.

DUpsample the audio recordings to 16 kHz. and transcribe the audio by using the Speech-to-Text API with asynchronous recognition.

Surprised that upsampling is even suggested, isn't 8 kHz enough?

I vaguely remember that asynchronous recognition might be more suitable for longer recordings, but I’m not entirely sure if upsampling is required.

I think we practiced a similar question where upsampling was mentioned, but I can't recall if it was necessary for the Speech-to-Text API.

Upsampling the audio to 16 kHz could be a good idea to improve the transcription accuracy, but I'll need to weigh the trade-offs between that and using the original 8 kHz sample rate.

Hmm, I'm a bit unsure about the differences between synchronous and asynchronous recognition. I'll need to review those concepts before deciding on the best approach.

I think the key is to follow the Google-recommended best practices, so I'll likely go with either option B or D that uses the Speech-to-Text API, since those are the ones explicitly mentioned.

I'm with the crowd on this one. Option D is the way to go. Though I do wonder if the audio quality will be as good as a human transcriptionist. Maybe we should hire some really bored linguists instead?
