Configuration of the Speech to Text feature consists of the following steps, detailed below:
Obtain a Nuance speech transcription account and conversion credits
Configure system-wide Speech to Text settings
Enable the Speech to Text feature
Configure Speech to Text for users
Nuance Communications is responsible for transcribing voice messages to text. To access this service, you require a user account and conversion credits, which you can obtain through your Authorized Mitel Reseller.
Contact your Authorized Mitel Reseller and provide the following:
User Name: Name of your NuPoint UM system.
System ID: Application Record ID, or ARID, of the NuPoint UM system.
Conversion credit quantity: Mitel sells conversion credits in prepackaged quantities.
Confirmation email addressess: Nuance sends a confirmation email to these addresses when conversion credits are purchased.
The information is sent to Nuance, which sets up your user account, assigns conversion credits, and sends you an email containing the following:
User Name: Same as above.
Password: Your unique account password, provided by Nuance.
Account ID: Your unique account ID number, provided by Nuance.
Application ID: Your unique application ID name, provided by Nuance.
Complete the next procedure, Configuring System-wide Speech to Text Settings.
These same credentials are used for account renewals. NuPoint UM does not know or report the state of your Nuance subscription. If your account is running low, Nuance notifies the NuPoint UM server, which in turn issues warning alarm messages. If your account is empty, the Speech to Text transcription service is terminated. You will need to purchase additional credits through your Authorized Mitel Reseller and then Activate Text to Speech.

From the navigation tree, click Unified Messaging > STT Configuration. If properly licensed, the Speech to Text configuration page is displayed.
Enter the following:
Username: Name of your NuPoint UM system.
Password: Your unique account password, provided by Nuance.

The STT feature is not a dictation service. While transcription accuracy can be very good, there may be instances when the transcription does not accurately represent the spoken message. If in doubt, listen to the original voice message.
Most callers do not speak in full and complete sentences; the transcription service will attempt to reflect this with spaces and punctuation.
Transcription quality depends on the clarity of the original voice message. For example, if the person has a heavy accent or does not speak clearly, or is speaking from a noisy from a noisy environment, then the message will not be transcribed correctly.
If the system cannot understand a voice message, it will not transcribe it. Instead, the user will receive an email notification. Typically, about 15% of messages are deemed "untranscribable."
The system is "tuned" to transcribe typical English conversation. In many businesses however, messages may contain jargon, phrases and acronyms that are difficult to transcribe.
The service is available in North American English only. For this reason, users who receive a significant number of voice messages in a different language should not be enabled for STT.
The maximum message length is 60 seconds. For longer messages, users can dial in and listen to the entire original voice mail.
