To check voice assistants mobile really simplify our lives, we have subjected to various tests. Mixed results …
We will have to get used to. Talking to a TV, give orders to the thermostat or washing machine, dictate a message to a tablet: all these uses will become as natural as talk loudly on the phone in the street. For now, smartphones are still the most iconic devices in the evolution of speech recognition in recent years. Need to tap on a keyboard or screen, just pronounce instructions to be obeyed by the device. These advances, especially appreciate the car, when you have to send an SMS without taking the phone in hand, and in all situations where it is not able to use your fingers. To assess progress, we tested the capacity of key current speech recognition systems on mobile: S-Voice on the Samsung Galaxy S5, Siri on the iPhone 5s, Google Voice on Nexus One with Android and 5 function Voice of Windows Phone with Nokia Lumia 1520
On each of these models, activates voice recognition easily. leave your finger on the physical Windows key with a Windows Phone, keep the bottom button down on the iPhone, double tap the “Home” button on the Samsung Galaxy S5 and say “OK Google” with a mobile Android. Once the instruction or question, some of them are able to read the answer or initiate a semblance of dialogue, asking to clarify information or to confirm a choice. Depending on the model, it is possible to select a male or female voice, with results not always very attractive, especially the Galaxy S5 whose robotic intonations are quite unpleasant. All need an Internet connection to transmit the sentence set forth in large computer systems that analyze and provide the appropriate response. No mobile or Wi-Fi network within range, do not expect your smartphone to be able to control his voice. Theoretically, speech recognition systems may include a simple question or a sentence in natural language. The machine adapts to humans, say engineers. In practice, it is sometimes the inverse. We must learn to make that request (infinitive or imperative?) And know what expression expects mobile. To run an application, for example, prefer a “launch” followed by the name of the application, the other includes only “start” and the third relies on the word “open.” Google loses control when asked “Wake me up tomorrow at 7:00″ or “Create an alarm at 7:00 tomorrow.” Only acceptable formula: “wake up at 7 am tomorrow morning me.” These little subtleties obviously detrimental to good agreement between the user and the device. However, in many cases, voice functions can render good services
● Telephone:. Equality iPhone 5s and Nexus 5
The four smartphones recognize commands without problem ‘type call 06 xx xx xx “or” Call Marc Dupont, “as long as the contact name appears in the Address Book. If asked to call “mom” without further explanation, all suggest to select a contact … with the exception of the iPhone, which then replies: “What do you call your mother?” Malin. And if you ask him to call “Domino’s Pizza”, which does not appear in the address book, the iPhone offers phone numbers of restaurants around this sign. Nexus 5, it automatically selects the nearest facility. As for the Galaxy, it displays a page containing the results of Internet contacts of the brand. Nokia, he answers “found contact”
● Dictating. Advantage Nexus 5
Our smartphones know how to take an SMS dictation and send. The Samsung Galaxy Nexus and iPhone even recognize phrases like “Warn Marc I’ll be late” or “Send a text message to Marc: I’ll be late.” Nokia, he proceeds in two stages, first responding to the command “Send SMS”, then waiting to be dictated text. The operation is more difficult for e-mails. The iPhone and the Nexus correctly interpret instructions as “Send an email to Marc Dupont, re: Meeting tomorrow message: As expected, the meeting will be held tomorrow in Building B”. Nokia to launch the application first app e-mail, then alternate pressing icons and voice dictation. S-Voice, it “does not offer this feature” …

● Order: iPhone head
In the case, the mobile can execute orders related to its operation. All agree to switch on the camera and launch an application (by choosing the right formula), but only the Galaxy and iPhone know activate airplane mode or Bluetooth when asked. With the exception of Nokia, our test models also agree to start playing music when you pronounce the name of a song or artist. The iPhone also starts without flinching playing a movie while the Galaxy does not include titles in English as Gravity or Wall-E, and the Nexus is determined to search the library’s online Play Movies. Finally, looking for a route unsatisfactory. Only the iPhone is doing well, showing both the path to go to that contact to join a company or a specific address
● Plan. Fuller iPhone
If all devices, except Nokia, know set the alarm an hour and a specific date, only
Galaxy S5 and iPhone 5s easily record an appointment following the instruction “Dinner Marc Dupont in Paris, Saturday 19 hours “and send the invitation to the corresponding contact. They can also respond appropriately to questions such as “What is my next appointment?” And “What time is my next meeting?”. Our smartphones can also take note of the voice comments when the word “Note” or used “Note that”. Original, Nokia retains the voice recording. But only the iPhone can create an alert that will be activated depending on the place after the command “Remind me to buy bread on the way home”
● Search. IPhone yet …
Ask a question, get the answer: it is one of the most spectacular voice recognition promises. Moderately promise held by our smartphones, which merely, in most cases, display a page of web results. Galaxy and iPhone stand out by providing a correct answer when asked what hours the Grevin Museum or how old Jean d’Ormesson are. But only the iPhone is able to offer a facility close after asking him to find a Chinese restaurant in the area. Finally, apart from Nokia, all can answer correctly when asked about the weather, including the coming days or a specific place. But only the Nexus and iPhone provide sports results without going through a Web page. Sometimes with humor: when asked about the final score of the PSG, Siri replied: “PSG has put head square in Montpellier with a score of 4-0 …”
