What do we want from a voice quality system? Let’s consider voice quality from a user point of view: We want to know when audio sounds good and when it sounds bad We want to be sure that if our customer uses our system to approach somebody the one at the destination will be able to communicate with the one at the origin We want to have a possibility to predict how our system will work when brought live We want to speak, hear and be heard We do not want to know HOW this is done, but we want to hear and be heard! Sound’s good!

Let’s consider voice quality from a user point of view:

We want to know when audio sounds good and when it sounds bad

We want to be sure that if our customer uses our system to approach somebody the one at the destination will be able to communicate with the one at the origin

We want to have a possibility to predict how our system will work when brought live

We want to speak, hear and be heard

We do not want to know HOW this is done, but we want to hear and be heard!

What do we want you to get from a voice quality system? Let’s consider voice quality from a user point of view: We want you to be able to automatically detect when audio sounds good and when it does not – and thereby be able to easily predict user satisfaction in your oraganization (and among your product and services users) We want to be sure that when your customer uses voice quality concept and software system and approaches somebody, the one at the destination will be able to communicate with the one at the origin with 100% satisfaction. We want you to predict how our system will work when going live We want your customers to speak, hear, be heard and satisfied with the quality We want you to be able to demand clarifications from your voice carrier provider (fixed, mobile, VoIP) referring to quantitative reasons for quality loss We want you to hear and be heard with a 100% satisfaction! Sound’s good!

Business Solutions (1): Automated IVR systems testing Check IVR System for: Voice services availability Announcements correctness Recognized prompt and prompt parts Entire architecture of your IVR system Define and create KPIs

Check IVR System for:

Voice services availability

Announcements correctness

Recognized prompt and prompt parts

Entire architecture of your IVR system

Define and create KPIs

Business Solutions (2): Automated IVR systems testing IVR System Under Test IVR system available Telecom equipment for making calls and DTMF input available Test scenarios known Audio recordings available Testing process Make call Create interaction (send DTMF tone) Receive voice response Compare received voice response with the correct (original) one Still doing this manually? Using expensive SR?

IVR System Under Test

IVR system available

Telecom equipment for making calls and DTMF input available

Test scenarios known

Audio recordings available

Testing process

Make call

Create interaction (send DTMF tone)

Receive voice response

Compare received voice response with the correct (original) one

Automate IVR systems testing Testing process Make call Create interaction (send DTMF tone) Receive voice response Compare received voice response with the correct one (original recording) by using Sevana Voice Quality Testing module: Original vs. Response = 80%-99% of similarity – correct! Original vs. Response < 60% of similarity – wrong! Otherwise – repeat test. Value: 1 test call takes 1 minute, 1 man hour costs 10 euros, amount of test calls 1000 (we know the numbers are really small!) Savings: over 166 euros, over 16 hours of work ROI: in reality after making 2001 test, this maybe less than 1 month!

Business Solutions(4): VQT in Mobile Networks Mobile device with a stored voice/audio of original quality initiating a call to “answering machine” Mobile network of any standard providing carrier to the “answering machine” and being reason for audio degradation “ Answering machine” when receiving a call plays back the same original audio to the mobile device Test network quality for voice transmission from a Windows Mobile enabled device in seconds! Mobile Network Originating a phone call Answering to phone call Playing recorded audio Receiving degraded sound

Business Solutions(5): VQ Monitoring Computer generating and storing “speech model” – a set of sounds typical for human speech – delivering to the reception side through carrier channel/trunk Network carrier: PSTN/GSM/3G/CDMA/IP Computer receiving degraded “speech model” and calculating voice quality value in % plus reasons for voice quality loss Test channels/trunks for voice quality continuously. No other equipment required than what you already have! Carrier Network Speech Model Signal Degraded Speech Model Signal

Business Solutions(6): VoIP: QoE Feedback Avoid asking VoIP users for voice quality feedback, automate receiving perceptual quality of experience values – make your system more customer friendly! On one end of VoIP conversation outgoing (original) and incoming (degraded) are recorded On the other end of VoIP conversation outgoing (original) and incoming (degraded) are recorded as well VoIP Network VQ Server tests original1 to degraded2 and degraded1 to original1 providing 2 values for voice quality of the conversation

Business Solutions(7): VoIP: QoS Monitor your VoIP provider by doing sudden tests and be aware that your provider maintains appropriate network and voice quality (especially if you signed SLA) Initiating a call would requite just the same client device/application and 1 license of Sevana Voice Quality Software Test voice quality in your VoIP environment and get back to your VoIP provider with questions on SLA and reasons for voice quality loss – you will be prepared with estimations and actual reasons what degrades voice quality in your network. VoIP network conditions as well as voice quality conditions may vary, but when you are paying for your VoIP provider you should have means to check the actual situation of voice quality in your VoIP VoIP Network Test HD Voice easily!
