Tutorial of Running Google Cloud Speech-to-Text Service on Local Computer

quick start (all article) Figure 0 $\colon$ Official Quickstart for Google Cloud Speech-to-Text Service

如Figur 0所示，Google官方有針對使用Client Libraries方式呼叫Speech-to-Text API的基本操作。我們針對Python部分的安裝特別說明。

Setup a GCP Console Project
- Create or select project
- Enable Google Speech-to-Text API for that project
- Create a service account
- Download a private key as JSON
Set the environment variable GOOGLE_APPLICATION_CREDENTIALS to the file path of the JSON file
```
export GOOGLE_APPLICATION_CREDENTIALS="[PATH]"
```
Install and initialize the Cloud SDK
- install $\colon$ ./google-cloud-sdk/install.sh
- initialize $\colon$ $:$ ./google-cloud-sdk/bin/gcloud init
  1. set/select configuration
  2. authenticate user account
  3. set GCP console project connection
Install the client library pip install --upgrade google-cloud-speech
Make a simple audio transcription request [1] by from google.cloud import speech

※ 值得注意的是，因為在anaconda的環境下，執行完第3步後，GOOGLE_APPLICATION_CREDENTIALS的值會被重新設定，所以我們在Realization時，第二步會跟第三步交換，意思就是先Install and initialize Cloud SDK後再export GOOGLE_APPLICATION_CREDENTIALS。
