AMD (Answer Machine Detection)
AMD (Automatic Message/Answering Machine Detection) is a system that identifies and filters out answering machines from live calls in call centres. It allows agents to only deal with customers and not voicemails.
What is Answer Machine Detection?
Answer machine detection is used in call centres to differentiate answer machines from humans. This machine focuses on detecting whether or not a call was answered by a human or an answering machine.
If and when the system detects a machine, it can either leave a pre-recorded message or hang up, depending on your preferences.
This is ideal, as it allows agents to move on to the next call easily without any downtime. The aim of AMD is to improve communication and optimise agent call time.
How Does AMD Work?
Now that you have a better understanding of what answer machine detection is, let's discuss how it works.
Firstly, the AMD system initiates an outbound call before analysing the audio. Next, the system detects the end of the ringback town and the beginning of the response.
The AMD system then listens to the first few seconds of the call to analyse speech patterns, pauses, and energy levels.
The system will use its algorithms before deciding whether the response is human or a machine.
If this system detects it is a human on the phone, then the call will be passed to a live agent or an appropriate IVR system where the call will be continued.
However, if the AMD detects an answering machine, then the system will either leave a pre-recorded message or terminate the call completely. This completely depends on your call centre's preferences.
The AMD system is based on three main principles; these include:
- Detecting a live caller saying something along the lines of 'hello...'
- Detecting background noise, such as hissing or rumbling (these noises are associated with a tape-based answering machine.
- Detecting a long sentence straight away, such as 'Hello, I'm sorry but I can't come to the phone right now...'
How Does AMD Differentiate Human Voices From Automated Recordings?
AMD is ideal for outbound calls and is used to differentiate human interactions from automated recordings, but how does this system do this? It's done through a range of methods, such as:
- Audio analysis: This is when the system analyses the characteristics of the call. It does this by listening to pitch modulations, tonal properties and frequency patterns.
- Algorithmic Processing: Answer machine detection works by using reliable algorithms that have been trained on datasets of recorded voicemails and real-time human responses so that it can make an accurate detection.
- Voice analytics: AMD systems utilise voice analytics to assess natural voice, vocal frequencies and specific patterns to recorded messages.
- Real-time assessment: AMD begins its real-time analysis when the call is initiated.
- Silence detection: Answer machine-detection systems work by analysing the first few seconds of a call to identify certain audio patterns and moments of silence.
- Customisable: AMD systems can be customised to meet the needs of different call centres. Parameters, such as machine detection timeout can be adjusted accordingly.
Answer machine detection systems use these methods to effectively differentiate between human interactions and automated recordings. This is ideal for outbound call centres as it can help to improve efficiency.
What is Answering Machine Detection Used for?
AMD is mainly used in telephony systems to improve the effectiveness of automated and semi-automated calling operations. Here are some of the situations AMD can come in handy:
- Call Centres: This system makes sure that humans are connected to live respondents in order to save time and resources.
- Automated Messaging Services: This system allows services to detect answer machines to make sure that the message is delivered on time even if the recipient is unavailable.
- Outbound Sales and Marketing: Sales teams can use AMD to focus on live calls rather than spending time on calls answered by machines. This is ideal as it maximises agent efficiency.
To sum up, answer machine detection is used to optimise the use of human and automated calls to make sure that live agents are directed towards live interactions.
What Are the Benefits of an AMD System?
An answering machine detection system offers a wide range of benefits that can improve the efficiency and effectiveness of telephone operations. Firstly, AMD ensures that human agents spend their time on live interactions to maximise productivity and minimise downtime.
Effective Communication
This system also automatically leaves pre-recorded messages on answering machines to make sure that their communication is efficient and consistent at all times.
Reduces Downtime
The calls that reach answering machines are detected quickly to reduce the downtime and overall call duration. This is also beneficial as it reduces any costs associated with the call.
Reduces Wasted Resources
Another advantage of this system is that it reduces any wasted resources. This is because it minimises the time agents spend on unproductive calls.
Improved Customer Experience
Answer machine detection also leads to an improved customer experience as it ensures that any important messages are delivered even in times when the recipient is not available.
Reduces the Likelihood of Multiple Call Attempts
This system is also ideal as it reduces the likelihood of multiple call attempts to the same number, which can be annoying for those receiving the call.
Better Reach
AMD is also ideal in marketing and sales campaigns, as it makes sure that human interactions are maximised at all times to improve the chances of successful engagements.
As you can see, AMD offers a wide range of benefits, from cost savings to operation efficiency and enhanced customer experience.
These benefits are some of the many reasons why AMD systems are an essential tool in modern telephone operations.
So, if you are looking to reduce downtime, improve communication and increase efficiency, then answer machine detection is the solution for you.
