# Commercial Use of macOS Say Command (TTS) Output is Prohibited

<div class="document">

<p>On a Mac,</p>
<pre class="literal-block">say --voice=Kyoko --output-file='/tmp/temp-audio.aiff' "こんにちは"
</pre>
<p>I thought about using the generated audio file created with a command like this for commercial purposes, but after some research, it seems it's not possible.</p>
<p>audio - Are the Apple text-to-speech voices copyrighted? - Ask Different</p>

<p>It says something like personal use is allowed, but commercial use is not.</p>
