<p>{{domxref("SpeechRecognition")}} インターフェイスの <strong><code>interimResults</code></strong> プロパティは interim の結果を返す (<code>true</code>) か返さない (<code>false</code>) か制御します。Interim の結果は最終的ではない結果になります (例えば {{domxref("SpeechRecognitionResult.isFinal")}} プロパティは <code>false</code> となる)。</p>

<p><strong><code>interimResults</code></strong> のデフォルト値は <code>false</code> です。</p>
