1. RECORD: Verify that the audio is being recorded correctly. Before posting to your application server, you can preview the recorded audio by using the <value> tag in a prompt. e.g.
Code: Select all
<record name="name" beep="true">
<prompt>
Say your name at the tone
</prompt>
<filled>
I heard, <value expr="name"/>.
</filled>
</record>
2. POST: If you are posting audio data to your application server to be saved, your application server must accept:
- method="post"
encoding="multipart/formdata"
3. AUDIO FORMAT: The audio data is always recorded as:
- format: headerless binary data
channels: mono
sample rate: 8 kHz
encoding: 8 bit u-law (mu-law) or 8 bit a-law coding, depending on the configuration settings for your PlumVP platform installation. Plum Voice Hosting uses the default setting, 8 bit u-law encoding.
