CRY TRANSLATOR / Research and development

Research shows that when parents respond quickly to soothe a crying infant, the baby cries less often overall. Scientific research demonstrates that infants who are nurtured and attended to by someone special have better social and cognitive skills as older children.

They are more inquisitive, confident, cooperative and independent than children who were not securely attached.

Crying is essentially a baby's first language. A baby cries to communicate his/her needs and feelings.

The American Academy of Pediatrics recognizes crying as a natural part of a baby's day. All babies cry, often without any apparent cause. Newborns routinely cry a total of one to four hours a day. No parent can console an infant every time he cries, but by paying close attention to a baby's different cries parents will be able to learn when the baby needs to be picked up, fed, tended, consoled, etc.

Research suggests five core cries are universal to all babies, regardless of culture or language. The five common cries are:

Hunger Sleepy Discomfort Stress Boredom

Every baby has a unique accent and tone, just as adults do. These inflections combined with a familiar cry pattern allow parents/caregivers over time to decipher their baby’s cries. For example, a stressed cry has a strong, short sound, falls slowly and then rises again, whereas a hungry cry is high-pitched and energetic.

The process of identifying and responding appropriately to a baby’s cry is achieved through a combination of instinct and learning. This process can take time especially for first time parents and caregivers. The sooner the parents can read their baby’s cues, the less anxious and more confident both baby and parents/caregivers will be.


The Cry Translator is the first application of a patented technology owned by Biloop Technologic, S.L. that can categorize a sound or noise signal in humans, animals and objects.

The Cry Translator is designed and piloted in Spain and patented internationaly.

The specialized sound microprocessor chip interprets any type of sound that is distinctive, repetitive and recognizable into a digital reading. The Cry Translator technology eliminates the use of patterns stored in memory with which signals are analyzed and compared. Instead, the identification process is carried out by means of a fuzzy logic algorithm.

The applications for this technology are diverse both within and outside the baby products industry. For example, this ground-breaking technology could be utilized in veterinary medical equipment, diagnostic medicine, industrial equipment, car industry and voice controlled systems, to name just some applications.

Dr. Antonio Portugal Ramírez, M.D. and Chief of Operations of Pediatric Services at Clinic Hospital Juaneda Menorca, Spain conducted a clinical study of the Cry Translator between December 15, 2008 and January 6, 2009. The objective of the study was to validate the diagnostic capability of the Cry Translator.

A total of 140 children from 0 to 2 years of age participated with a random sample of 104 children used in the analysis. Of those included in the test group;

> 54% of participants were male; 46% female

> 72% originated from Europe, 4% Sub-Saharan, 4% asian and 8% Latino Americans

> 77 % of the tests were conducted with children who visited the Clinic

> 33 % of the tests were conducted with children hospitalized in the Clinic

The pediatric team leading the study placed the Cry Translator device about 1 meter (~3 feet) from the crying child. The pediatrician allowed 5 seconds for analysis, ensuring no background noise was present. Based on the corresponding emotional or physiological state, the applicable suggestions to calm the child were followed. The baby’s response to the suggestions was evaluated immediately and monitored to see if it remained stable for a period of time. The devices’ diagnosis was deemed accurate if the baby was calmed following the suggested tips in response to the cry.


The team found that 96% of the babies ceased crying after following the suggestions indicated on the symptom chart associated with the Cry Translator. The remaining 4% of participants did not respond accordingly.

The following conclusions were observed and documented:

1. In about three seconds the Cry Translator from Biloop Technologic was able to identify why the infant was crying.

2. Statistically significant differences were not established in the identification of the cause of the crying based on ethnicity of the child. The characteristics of a child’s cry appear to be universal based on their needs and emotions.

3. The Cry Translator was deemed an efficient device to accurately translate a baby’s cry. All participating doctors felt the device will help parents and caretakers to comfort and calm a crying baby more quickly and effectively.

A European Notary’s Account of the Accuracy of the Cry Translator

European Notary Mrs. Teresa Castillo Moreno writes in her independent validation of accuracy; Throughout the duration of the tests carried out, I notice that when I move the compact disk player too close to the translator device, a message appeared on the screen of the translator device that read “WARNING: too CLOSE”. I then moved the device away. I again pressed the button “ENTER”, thereby restarting the reading of the crying sound from the compact disk and translation began. The message that appeared on the screen read “Translating Crying”. In the case of the player being too far away or for any other reason that translation of the crying sound was not taking place, the message, “Press ENTER” appeared on the screen, and after pressing the “ENTER” button the message once again appeared on the screen that read “Translating Crying”


"The result of tests carried out were as follows: twenty tests of crying type HUNGER, for which there were matches in all cases; twenty tests of crying type TIREDNESS, for which there were matches in all cases; twenty one tests of crying type DISCOMFORT, for which there were matches in all cases; twenty tests of crying type STRESS, for which there were matches in all cases; and nineteen tests of crying type BOREDOM all of which matched".

So, in conclusion, the accuracy level without background noise is 100%.

North American Market Research

In 2005, Biloop Technologic, S.L. conducted a product field study to test receptivity to the Cry Translator in the North American environment. The purpose of the field study was to confirm the product’s analytical effectiveness in order to assess its attractiveness to the North American consumer.

The team that conducted the field study adhered consistently to the operating instructions provided by the developer, Biloop Technologic, S.L. in order to formulate the methodology for testing the Cry Translator. Testing and surveying was conducted in a variety of urban locations.

> Private residences

> Commercial Day care facilities

> Private Day care facilities

> Commercial centers

> Shopping malls

> Restaurants

> Random passersby (Street polling)

Researchers recorded the test subjects several times and had subjects test their babies themselves with detailed operating instructions. The processes involved either a one-time session with mother and child to test the unit or the subjects used the device for a period of one week. During the one-week sessions, the mother was required to fill out a questionnaire and log the sessions. Multiple readings were conducted throughout the week. The mothers were also required to strictly adhere to the instructions provided by Biloop Technologic, S.L.


At the completion of the study, a total of 856 readings were recorded. The results obtained indicated that the Cry Translator was over 90% accurate.

Based on the level of accuracy discovered upon the completion of the study and the Cry Translator unit’s attractiveness to the average North American parent, Biloop Technologic, S.L. deemed the Cry Translator unit a most viable product and worthy of investment. This market research indicates there is enormous mass market appeal for a product that helps parents learn how to decipher their baby’s first language – their cry.
