How Does Answer Machine Detection Works?
Now that you know what answering machine detection is, we're betting that you want to know how it works. You're in luck! You've got questions, and we've got the answers. AMD detection detects whether or not a live call is taking place based on speech, silence, and duration.
Algorithms analyze these factors to determine whether it's a human or machine on the other end of the line. Voicemails usually contain a long string of words with little silence, while live callers answer the phone and then wait for a response.
Tips for Leaving Voicemails
Keep your voicemails short, simple, and to the point. People lead busy lives and have short attention spans. If a voicemail is overly long or vague, people will delete it.
Did we mention that people will also delete voicemails if they sound automated or boring? Make sure your voicemails are personable and friendly.
Speak clearly and concisely when leaving a voicemail so understand. This also means making sure background noise doesn't overpower your message.
Let's Break It Down: Voicemail Vs. Live Caller
Scenario 1: Voicemail
“Hi, this is John Doe. You just missed me, please leave a message at the beep.”
In this scenario, a voicemail would immediately begin playing. Voicemails are usually lengthier than greetings from live callers and have less pauses. The cadence of your voice is often steadier, with less variation in volume and emphasis. If you don't have a recorded voicemail and instead rely on the default voicemail, this is especially true. The algorithms would pick up on this and correctly detect an answering machine.
Scenario 2: Live Caller
“Hello, this is Jane Doe. … Hello? … Is anyone there?”
Opposite to the previous scenario, a person picks up this time and a live call is initiated. There is usually a short salutation and then silence as you wait for an answer. This may repeat once or twice as you continue to wait. The pitch of your voice may go higher or lower, emphasis may be placed on certain words, and your tone may change. The algorithms would analyze these factors and then label the call as live.
Scenario 3: AMD Accuracy
It's important to note that AMD isn't 100% correct all of the time. Answering machine messages vary and can sometimes be mistaken for a live caller depending on the voicemail. Additionally, factors such as the tone of your voice (or voicemail), background noise, music, and sine tones all affect answering machine detection and its accuracy.
