Keyword Spotting uye Wake Mashoko
Keyword spotting ndiyo inogara ichiteerera tekinoroji inoita kuti mudziyo umirire mutsara mumwe chete wekusimudza senge 'Hey Siri' kana 'Alexa' isati yatanga kuita.
Pfupiso
It matters because it makes hands-free voice control possible while keeping power use and privacy intrusion low.
Kudzika Kwakadzika
A wake-word detector idiki, specialized kutaura modhi ine basa rekupindura mubvunzo mumwechete kakawanda pasekondi: mushandisi achangotaura mutsara wekutaura here? Kusiyana nekuzivikanwa kwekutaura kuzere, hainyori zvese - inomhanyisa diki neural network yakananga pachishandiso, ichiongorora mapfupi anoputika mahwindo eodhiyo. Kuchengetedza bhatiri, nharembozha uye vatauri vakangwara vanowanzo shandisa dhizaini ine-matanho maviri: iyo yekupedzisira-yakaderera-simba chip inoteerera kune yakakasharara match, yozomutsa modhi yakati kurei kuti isimbise isati yafambisa chero chinhu kune gore. Mainjiniya vanogadzira chikumbaridzo kuti vaenzanise kubvuma kwenhema (kumuka kana pasina munhu akafona) vachipikisa kurambwa kwenhema (kuregeredza murairo chaiwo), uye vanodzidzira zviuru zvematauriro, madaro, uye makamuri ane ruzha.
Technical Insight
Inouya odhiyo inochekwa kuita ~ 20-40 millisecond mafuremu uye inoshandurwa kuita maficha akadai seMFCCs kana mel filterbank simba. A compact neural network - kazhinji kacho kadiki keshanduko kana inodzokororwa modhi, dzimwe nguva ichishandisa zvakadzika-inopatsanurika convolutions kuti ideredze saizi - inoburitsa mukana wechirevo chechirevo chega chega. Nhanho yekumashure-inotsvedzerera kana kutsvedza-hwindo inodzivirira mafuremu ane ruzha kamwe chete kubva pakumuka, uye moto wekuona unobvira chete kana chivimbo chikaramba chiri pamusoro pamafuremu akatevedzana.
Strategic Impact
Svika uye svika
Inonatsiridza kusvikika kuburikidza nekunyora, kurondedzera, uye mazwi ekubatanidza.
Mutengo uye bhajeti
Zvikwata zveMedia zvinogona kutumira odhiyo yakakwenenzverwa nekukurumidza nemabhajeti madiki.
Kumhanya uye chiyero
Masisitimu anotarisana nevatengi anogona kugadzirisa kutaurirana kwekutaura pamwero mukuru.
Ramangwana reMashoko Akakosha uye Wake Mazwi
Wake-mazwi modhi ari kuita madiki uye akawedzera ega. Kudzidza pa-mudziyo kunokubvumira kuti unyore mitsara yekukonzeresa mitsara uye uchinje kune rako pachako izwi pasina kutumira odhiyo chero kupi. Tarisira kubatanidzwa kwakasimba nesilicon yakaderera-simba, mitauro yakawanda uye kodhi-kuchinja, uye kusimba kuri nani kumaTV, mimhanzi, uye kure-kumunda ruzha. Madhizaini ekuchengetedza zvakavanzika anochengeta vese vanoteerera vemunharaunda - kusimbisa izwi rekumuka pamberi pese network yekubatana - yave kuita tarisiro yekusagadzikana.
Real-World Implementation
Kutaura 'Alexa' kuAmazon Echo kana 'Hey Google' kune mutauri weNest kuti utange kukumbira izwi risina maoko
'Hei Siri' kumutsa iPhone kana AirPods kubva pakakiiwa, yakaderera-simba mamiriro pasina kudzvanya bhatani.
Mota infotainment masisitimu inoteerera mutsara wakaita senge 'Hey Mercedes' kuitira kuti vatyairi vagadzirise kufamba vasina kubvisa maoko pavhiri.
Chipatara uye mahedhifoni edzimba anobatidza pamurairo unotaurwa kuti vashandi vagone kunyora data nemagurovhosi uye maoko azere.
Njodzi & Guardrails
Kushandisa izwi zvisizvo uye njodzi dzekuedzesera dzinowedzera kana chibvumirano chisipo.
Kururama kunogona kudonha mumitauro, mataurirwo, kana nharaunda dzine ruzha.
Synthetic audio inogona kukanganisa kutaura kwechokwadi isina mavara akajeka.
Implementation Roadmap
Wana mvumo yakajeka yekutora inzwi, kugadzira, uye kushandisa zvakare.
Yedza mhando pavatauri vakasiyana uye mamiriro ekumashure.
Tsanangura apo munhu anofanira kuongorora kana kubvumidza zvabuda.
Label synthetic odhiyo uye chengetedza marekodhi ekuzvidavirira.

What is Keyword Spotting and Wake Words?
Keyword spotting ndiyo inogara ichiteerera tekinoroji inoita kuti mudziyo umirire mutsara mumwe chete wekusimudza senge 'Hey Siri' kana 'Alexa' isati yatanga kuita. Izvo zvine basa nekuti zvinoita kuti maoko-emahara kudzora inzwi kugoneke uchichengeta kushandiswa kwesimba uye kuvanzika kupindira kwakaderera.
Ndeipi basa rekutanga rewake-word detector?
A wake-word detector hainyori zvese; inongoratidza chete kana mutsara wakasarudzwa wemutsara wataurwa kuitira kuti system huru igone kumuka.
Nei vazhinji vatauri vakangwara vachishandisa dhizaini yekuona-matanho maviri?
Chikamu chidiki-chesimba chinoteerera nguva dzose uye chinongomutsa modhi inokwanisa kusimbisa, izvo zvinoita kuti kushandiswa kwesimba kurambe kwakadzikira.
Ko 'kubvuma kwenhema' kunorevei mukuonekwa kwemazwi?
Kubvuma kwenhema ndiko kukonzeresa kusingadiwe - sisitimu inoshanda kana izwi rekumuka risati rataurwa. Zvakapesana kurambwa kwenhema.
Zvinei kuti iyo inouya yakagadziridzwa sei iyo neural network isati yazviona?
Odhiyo yakatsemurwa kuita mapfupi mafuremu (makumi emamilliseconds) uye anoshandurwa kuita compact maficha modhi inogona kukora furemu nefuremu.
Sei kuwonekwa kuchiwanzoda ruvimbo rwepamusoro pamafuremu akati wandei akatevedzana?
Kutsvedzerera pamusoro pemafuremu akawanda kunomisa mapfupi mapikisi eruzha kubva pakupfura detector, zvichivandudza kuvimbika.
