A new app aims to help parents interpret what their baby wants based on the sound of their cry. The free app ChatterBaby, which was released last month, analyzes the acoustic (声学的) features of a baby’s cry, to help parents understand whether their child might be hungry, fussy or in pain. While critics say caregivers should not rely too much on their smartphone, others say it’s a helpful tool for new or tired parents.
Ariana Anderson, a mother of four, developed the app. She originally designed the technology to help deaf parents better understand why their baby was upset, but soon realized it could be a helpful tool for all new parents.
To build a database, Anderson and her team uploaded 2,000 audio samples of infant(婴儿) cries. She used cries recorded during ear piercings and vaccinations to distinguish pain cries. And to create a baseline for the other two categories, a group of moms had to agree on whether the cry was either hungry or fussy.
Anderson’s team continues to collect data and hopes to make the app more accurate by asking parents to get specific about what certain sounds mean.
Pediatrician Eric Ball pointed out that evaluating cries can never be an exact science. “I think that all of the apps and technology that new parents are using now can be helpful but need to be taken seriously,” Ball said ,“ I do worry that some parents will get stuck in big data and turn their parenting into basically a spreadsheet(电子表格) which I think will take away the love and caring that parents are supposed to be providing for the children. ”
But Anderson said the aim of the app is to have parents interpret the results, not to provide a yes or no answer. The Bells, a couple using this app, say it’s a win-win. They believe they are not only helping their baby now but potentially others in the future.

It was hard to accept, but the sad day had finally arrived. I still remember the tears welling up in my six-year-old sister’s eyes as she looked around the empty closet in wonder. The space once filled with her clothes now held only loneliness and sorrow. This little child had come to the realization that her father was gone. He had left us, and there was simply no way to change it.
Being the oldest of four girls has never been easy, but with the departure of our father, our world and dreams were broken beyond repair. My mother, the most amazingly warm-hearted person in the world, has worked harder than anyone should simply to mend our broken household. However, long hours at work often prevented her from physically being there in our times of need. This is where I have stepped up as the temporary caretaker of my three small sisters.
Many students write college essays about their leadership positions in school and the community but I feel that my greatest accomplishment is the role I have played within my own family.
Senior year in high school is not simple for anyone, especially when it feels like the entire world is resting on your shoulders, but this is how I have felt for the past two years, I have continually tried to fulfill the dream my mother holds for my future. My mother was not able to complete her college education, and so this success is her top significance for her children.
A leader is defined as one who has influence on others. I hope that my leadership affects the lives of my sisters and everyone around me. In dedicating myself to my family and school, I have set goals that I will do anything to accomplish. I am an extremely determined individual, and my university will help me take the next step in climbing the ladder of success.
