These different decisions and determinations may be obtained in several ways. For example, different parameters received from a different component may be combined in a predetermined way, for example, using predefined weights. Alternatively, a neural network may be provided to which these parameters are passed and which outputs the corresponding decisions and determinations. Therefore, the a posteriori probability of GMM λ1 is reduced due to the uncertainty of the given feature vector with respect to the classification into speaker or background noise. This results in a further parameter of the speaker adaptation control. The covariance matrices need not be fused as only the weights and mean vectors are adapted in the MAP algorithm.

Data storing and security methods
The first device, Google Home, was released in the United States in November 2016; subsequent product releases have occurred globally since 2017. Feature vectors of a received speech input may also be buffered in buffer 103 to be used by other component during subsequent processing. The number of speech inputs or utterances for which speech vectors are buffered may be limited because of computational load requirements or privacy protection. The buffered feature vectors are used to collect enough utterances for reliable detections, for example, for speaker change recognition for which particularly one or more directly preceding utterances are employed. The method may comprise comparing a speaker model in the speaker model set before and after the adapting step according to a predetermined criterion. This comparing step may comprise determining a distance of the speaker model before and after the adapting step.
Speaker Recognition is an emerging technology which has become quite popular due to its practicality of implementation in an existing telephone infrastructure, and the capability of remote biometric authentication. It is a multidisciplinary subject with information scattered throughout different research publications and textbooks. Speaker Recognition is getting more and more known for providing voice authentication over the telephones for helpdesks, call centers and other enterprise business for business process automation. Technology is evolving to support the consumer end solutions, where people have to understand the fundamentals of speaker recognition. This universal background model may be stored, for example, in a separate storage unit which is accessible by the different components of the apparatus illustrated in Fig.
Which voice control system is best for your home? Google or Amazon?
However, you can enhance the speaker’s voice recognition capability with a few easy pointers. When you turn on Voice Match, you can teach Google Assistant to recognize your voice so it can verify who you are before it gives you personal results. You can turn on Voice Match for a home or specific Assistant-enabled devices, like a speaker, Smart Display, or Smart Clock. Up to 6 people can turn on Voice Match for one home in the Google Home app. If you want a small display that's focused on telling the time above all, Lenovo's Smart Clock (7/10, WIRED Recommends) is the way to go.
When you can hear every layer and every single lyric of your favorite song, it enhances the listening experience. Sound effects can help to immerse you in Google Home’s audio games, and make you feel like you’re actually in the fictional world. Apparatus according to claim 16, wherein the detecting component additionally comprises a control component configured to control the detecting step based on received input data. Method according to one of the preceding claims, wherein the maximum number of speaker models in the speaker model set is limited. 1 illustrates schematically the structure of an example of an apparatus for speaker recognition; Fig. 2 illustrates a flow diagram of an example of a method for speaker recognition; and Fig.
Models
If you plan to use your speaker in a noisy workshop, the Home’s voice recognition might work a little better. Brent also ran some lab tests on the speakers to confirm what everyone heard. Because the Home had neither input jacks nor Bluetooth capability at the time of testing—which would have allowed it to accept test signals from an audio analyzer—Brent had to perform the tests using a pink-noise track sourced from Spotify. He measured each speaker from the same eight locations in his listening room and then averaged each set of eight measurements to minimize the effects that the acoustics of his listening room had on the speakers’ performance.
Then, the likelihoods are fed to this neural network to perform the speaker recognition based on these input variables. In this way, the speaker identification constitutes another suitable parameter for the predetermined criterion. According to a further step 205, a speaker adaption is performed in speaker adaption component 106. If a presence of a known speaker has been determined in control component 102, the identified existing speaker model in the speaker model set is adapted using the above-described maximum a posteriori method.
It features a 10-inch display, integrated camera , and larger speakers with a rear-facing subwoofer. Prior to its release, a "phantom input" bug was discovered, where its touch-sensitive surface—which could be tapped to activate Assistant without using a hotword command—inadvertently activated on its own, resulting in unwanted voice recording. Due to privacy concerns, Google removed the feature entirely from all units via a software update. In December 2017, Google released an update to Home Mini, allowing users to long-press the volume buttons to play and pause audio. The original Google Home model is a cylindrical speaker that is 5.62 inches tall and 3.79 inches in diameter.
A voice control system is one popular technology to add to your home in 2022. You can pair another Sonos One to get multiroom stereo sound, and if you have other Sonos speakers in your home, like the company's soundbars or larger speakers, it can seamlessly connect to them. The Sonos Move (8/10, WIRED recommends) is also a nice option from Sonos (and it's portable!), but it's twice the price. Method according to one of the preceding claims, wherein the speaker-independent model is a Universal Background Model.
Various forms of both in-house and third-party services are integrated into Google Home, allowing users to speak voice commands to control interaction with them. Considering that this smart speaker comes from a company that both makes smart-home devices (Nest’s thermostat, camera, and smoke alarms) and helped design a smart-home protocol , you might expect it to include integration skills from the start. At launch, Home worked with Philips Hue smart lights, the Nest Learning Thermostat , Samsung’s SmartThings Hub, and the integration cloud service IFTTT. Other device integrations came later, including Wink and Harmony smart-home hubs, August locks, LIFX bulbs, and TP-Link bulbs and switches.
If you have multiple Google Accounts, you can choose which account you want to use. When the alarm is ringing, just say "stop" and the blaring sounds will cease—no "hey Google" needed. For a more tactile touch, thump the top of the clock to trigger snooze mode. If you're looking for the most affordable way to smarten up your home, the Nest Mini is where you should start. It's definitely worth a few bucks more than the original version, which is still available at some retailers.
Users can connect and group together multiple Home speakers for synchronized playback of music in every room. A notable feature omission, multiple accounts, was criticized by JR Raphael of Computerworld in November 2016, but an update for users in the United States in April 2017 enabled the feature. Google Home can now recognize up to six different voices, pulling information from their different accounts depending on who's talking. Google Home has integration with each user's calendar, for adding reminders or appointments verbally. The Google Home smart speaker was released in the US on November 4, 2016, and in the UK on April 6, 2017.
Best of all, there's a physical switch on the back that turns off the mic and camera. By the factor α, a weighting over the number of "softly" assigned feature vectors is obtained so that the adaption step is proportional to the number of assigned vectors. Clusters with a small number of adaption data are adapted slower than clusters for which a large number of vectors was available.

Method according to one of the preceding claims, wherein the detecting step is based on a Bayesian Information Criterion. It is to be understood that the different steps and components described above may also be combined in a different way and need not always be present altogether.
