When I was 13, my journey in a great valley changed my attitude towards the recording of a travel. During the trip, I was busy recording every event, name and place I came across. I felt proud to {#blank#}1{#/blank#} my time, keeping a {#blank#}2{#/blank#}description of my travels. On my last night there, after I {#blank#}3{#/blank#} the tent, I went out with diary in hand. The sky was clear with the bright moon, and the walls of the valley looked frightening behind their curtains of shadows（阴影）. The beauty of nature at dusk {#blank#}4{#/blank#} my heart entirely. I took out my pen right away... At that moment, I understood that the beautiful scenery I saw {#blank#}5{#/blank#} was more meaningful than the tiring words that I had {#blank#}6{#/blank#} in my diary. Since then I have {#blank#}7{#/blank#} only to keep a special thought or feeling in my diary. The unforgettable moments I {#blank#}8{#/blank#} would be the sweet and lasting memories for my life.

Very frequently voice analyst have a stake at deciphering the relevant information which may be {#blank#}8{#/blank#} with background noise or other interfering sounds until they attain the {#blank#}9{#/blank#} results.

    Thankfully, these efforts help the police detect individuals who threaten their victims by phone or inform about bomb {#blank#}10{#/blank#} or those who make offensive calls disturbing the peach of decent citizens.
