How to use java-google-translate-text-to-speech api?
<p>I read one answer here (<a href="https://stackoverflow.com/questions/8147284/how-to-use-google-translate-api-in-my-java-application">How to use Google Translate API in my Java application?</a>) and started to use java-google-translate-text-to-speech api as it is free.</p>

<p>But when I use this api in a standalone java file, I am facing an issue : "Your client does not have permission to get URL /translate_a/t from this server. That’s all we know." HTTP Reponse Code 403-Forbidden error.
Do I need to use API key to use this api ?
Is there any sample code which uses API key ?
I am posting a question for the first time so apologies if the formatting is incorrect.</p>

<p>Thanks in advance !!</p>
