{% hint style="info" %}
Confidence values are defined in percentage from 0 to 100%. When confidence value is not available 0 or -1 can be returned.
{% endhint %}

{% hint style="warning" %}
Android does not have a continuous mode option. Kalipso will loop internally to emulate a continuous mode, so the recognition may not work as well in this mode.
