In a simple audio element with alternate TTS text, can one determine whether the alternate text was spoken? It seems the spec is silent on this, and I have found the question of whether the alternate content is evaluated to be interpreter-dependent. For example: <block> <var name="ttsfail" expr="false"/> <prompt> <audio expr = "vox_file('greeting.wav')"> <value expr="ttsfail = true, ''"/> Thank you for calling ... Your call is very important to us and may be monitored or recorded for training and quality control. </audio> </prompt> <!-- execute following prompt only if the greeting.wav fetch failed and text inside the above audio element was spoken. greeting.wav has a dual language recording, so this provides dual language TTS backup. However, interpreter appears to evaluate inside the audio element even if the content is not used --> <prompt cond="ttsfail" xml:lang="es-MX"> Gracias por llamar ... Su llamada es muy importante para nosotros y podrá ser monitoreada o grabada para capacitación y control de calidad. </prompt> </block> The question is under what circumstances is the variable ttsfail set to true?
