Speech and audio
11 milestones used this technique.
CIMON Launched to the International Space Station
In June 2018, DLR, Airbus, and IBM launched CIMON (Crew Interactive Mobile Companion), a spherical, voice-controlled AI assistant, to the International Space Station aboard SpaceX CRS-15. It was designed to support ESA astronaut Alexander Gerst with procedural tasks and reduce cognitive workload.
WaveNet: A Generative Model for Raw Audio, by DeepMind
In September 2016, researchers at Google DeepMind published WaveNet, a deep generative model that synthesises raw audio waveforms sample-by-sample using dilated causal convolutions. In evaluations on English and Mandarin speech, WaveNet reduced the gap between human speech and machine synthesis by more than 50 per cent compared with the best previous text-to-speech systems.
Amazon Introduces Alexa and the Echo Smart Speaker
In November 2014, Amazon introduced Alexa, a cloud-based voice assistant, alongside the Amazon Echo smart speaker. Alexa accepted natural-language voice commands for tasks including music playback, information retrieval, smart-home control, and calendar management, bringing always-on voice interaction into consumer homes at scale.
SoftBank Robotics and Aldebaran Unveil Pepper, a Humanoid Robot with Emotion Recognition
In June 2014, SoftBank Robotics and its subsidiary Aldebaran Robotics unveiled Pepper, a 1.2-metre humanoid robot equipped with an emotion-recognition system capable of detecting human facial expressions, voice tone, and body language, intended for retail and customer-service deployment.
Kirobo Robot Launched to the International Space Station
In August 2013, a consortium comprising the University of Tokyo, Toyota Motor Corporation, Dentsu Inc., and JAXA launched Kirobo, a small humanoid robot capable of speech recognition and natural-language conversation, to the International Space Station aboard HTV-4 to serve as a conversational companion for Japanese astronaut Koichi Wakata.
Apple Releases Siri with iPhone 4S
On 4 October 2011, Apple announced Siri as an integrated feature of the iPhone 4S, making a conversational voice assistant, capable of natural-language queries, task execution, and third-party service calls, available to a mass consumer audience for the first time at that scale.
Dasarobot Genibo QD Consumer Pet Robot
In April 2006, South Korean company Dasarobot unveiled the Genibo QD, a consumer pet robot modelled on a dog and equipped with cameras, infrared sensors, and voice-recognition software designed to simulate emotional responses to its owner.
Kismet: Sociable Robot Developed by Cynthia Breazeal at MIT
Around 2000, Cynthia Breazeal at the MIT Artificial Intelligence Laboratory completed Kismet, a robotic head capable of perceiving and expressing emotion through coordinated facial features, pioneering research into socially intelligent robots able to engage in natural affective interaction with humans.
WABOT-2 Humanoid Robot Demonstrated at Waseda University
In 1984, researchers at Waseda University in Japan completed WABOT-2, a humanoid robot capable of reading printed musical scores, communicating with a human performer via speech, and playing an electronic organ using its fingers and foot pedals at a level comparable to an average adult pianist.
2001: A Space Odyssey Released, Featuring HAL 9000
In April 1968, Stanley Kubrick and Arthur C. Clarke's film 2001: A Space Odyssey introduced HAL 9000, a fictional shipboard AI capable of natural speech, lip-reading, chess play, and autonomous decision-making. The portrayal became a lasting cultural reference in debates about machine intelligence, autonomy, and the risks of over-reliance on automated systems.
IBM Shoebox Speech-Recognition Device Demonstrated
In 1962, IBM publicly demonstrated the Shoebox, a hardware device capable of recognising sixteen spoken English words, the digits zero through nine plus six arithmetic commands, and using that input to drive a calculating machine in real time, showing that limited-vocabulary speech recognition was mechanically feasible.
