Re: Polly Voices Options

Thank you for the reply. Having that as a global property (or some other way to set it as the default) would be a great addition to the platform. But either way, this is good news. Thanks again.

Polly Voices Options

Hello, I noticed that Polly voices are now available - not only as an option for the application, but there is also documentation on the dev site. My first question is: is Polly now fully supported as a TTS option? We have tested some options (like Nuance Vocalizer 6.0 Alpha) that work sometimes, bu...

Long call recordings break the recording downloader

At the end of every call, I send the recording to a file (SaveCallRecording.php) to convert to WAV (using SOX) and save. After a long call (both my tests were about 1 hour 20 min), it is throwing an error: DocumentParser::FetchDocument - Parse error in file "/IVR/SaveCallRecording.php", line 1, colu...

Re: Recordcall appending empty recording

Support said this is indeed a platform issue and is slated to be resolved in a future release. The workaround I came up with for my specific situation is to use SOX to trim the silence at the end of the call. See the SOX documentation for "silence" for more information. Here is the full SOX command ...

Re: Recordcall appending empty recording

I sent in a request to support, but thought I would give an update here. I determined this is because of the <disconnect/> tag in the Hangup form. If I use a <throw event="connection.disconnect"/>, the recording works as expected. However, I am using disconnect very intentionally - I want to hang up...

Recordcall appending empty recording

My application (among other things) connects the caller to a third party via <transfer>. At the AppRoot level, I have the recordcall property turned on, as the entire IVR portion of the call is recorded. However, for some transfers, we want to turn off recording. The transfer is essentially the end ...

Re: Unexpected result returned from grammar

I see that your test was successful. We did more testing from different phones, with different people, and different pronunciations. We have received mixed results, even when speaking very similarly between calls on the same device. From our desk phones, it seems to work pretty consistently. From ou...

Re: Unexpected result returned from grammar

Sent a PM with instructions on testing.

I recently noticed that I can actually have two grammars of different languages active at the same time, and this worked with Recognizer. Is this a supported scenario?

Re: Unexpected result returned from grammar

Thanks, switching to OSR fixed that issue. However, I cannot get OSR to properly recognize my Spanish utterances. "Lámpara" returns "llama" every time. "Manzana" returns "llama" as well. Do you have any more information on the differences between these engines, with regards to accuracy and multiling...

Re: Unexpected result returned from grammar

We are using the AT&T Natural Voices 1.4, but I have also tried Realspeak 4.0, I believe. We plan on using Nuance Vocalizer when that is released. I have this as an XML file in Plum File Repository for my account under /testgrammars/SpanishEnglishTest.xml. I have it saved as UTF-8, as that sounded l...

Unexpected result returned from grammar

I am testing Spanish speech recognition, and have run into an issue. This is the code I am using: <?xml version="1.0" encoding="utf-8"?> <vxml version="2.1" xml:lang="es"> <form> <field name="keyword"> <grammar type="application/srgs+xml" root="KEYWORDEN" mode="voice" xml:lang="en"> <rule id="KEYWOR...

Re: Property 'recordcall' not recording part of the call

Thank you for your response. Our business leaders and QA team have a requirement that the audio recordings of the entire call sound exactly like the actual call (all sounds and whitespace included). I already noticed that whitespace seems to be truncated (i.e. if there is an extra long fetch in the ...

Re: Property 'recordcall' not recording part of the call

Thanks for the response. We do utilize the <record> tag, where appropriate. However, I am looking to record the entire call (including complicated IVR prompts, etc), so the <record> tag is not what I am looking for here. Also, I cannot put a <subdialog> in a <record>. The place where the call is not...

Re: Property 'recordcall' not recording part of the call

Thank you for the reply. I changed this setting to "true", and now it does record the beginning missing prompts. So we are partially there. I didn't mention this in the OP, but this setting is disabled because I 'split' the recordings into multiple files in the following manner: Start recording at b...

Property 'recordcall' not recording part of the call

I am having a problem in which part of my IVR flow is not being recorded as expected. Here is the (extremely) simplified structure of my application: AppRoot.php: <?php echo "<?xml version=\"1.0\" encoding=\"UTF-8\"?>"; ?> <vxml version="2.1"> <property name="recordcallappend" value="false"/> <prope...
