public String getLanguageCode() {
        return this.languageCode;
    }
<p>
Optional language code for a synthesis task. This is only necessary if using a bilingual voice, such as Aditi,
which can be used for either Indian English (en-IN) or Hindi (hi-IN).
</p>
<p>
If a bilingual voice is used and no language code is specified, Amazon Polly uses the default language of the
bilingual voice. The default language for any voice is the one returned by the <a
href="https://docs.aws.amazon.com/polly/latest/dg/API_DescribeVoices.html">DescribeVoices</a> operation for the
<code>LanguageCode</code> parameter. For example, if no language code is specified, Aditi will use Indian English
rather than Hindi.
