How do you say 私は以前、通訳でした。通訳は会話を全く有るがままに訳し、自らの考えを持たない機械のように振る舞わなければなりません。これが退屈で私はこの仕事を辞めたのです。 in English?

I used to be an interpreter. Being an interpreter requires to act like a machine, which doesn't have its own idea, interpreting their conversation exactly as it is. This boredom made me quit the job.
