摘要： A system and method for performing text-to-speech (TTS) processing of textual works, such a literary works. The system and method process text of these works and determine offsets corresponding to one or more of chapters, paragraphs, sentences, words, section of dialogs, sections of other context. Using these offsets, the system and method determine which portion and how much of a work to process using TTS processing at a time to produce a high quality audio output. This audio output may then be sent to a user device to allow the user device to play the audio output of the TTS processing.

摘要： A system has multiple audio-enabled devices that communicate with one another over an open microphone mode of communication. When a user says a trigger word, the nearest device validates the trigger word and opens a communication channel with another device. As the user talks, the device receives the speech and generates an audio signal representation that includes the user speech and may additionally include other background or interfering sound from the environment. The device transmits the audio signal to the other device as part of a conversation, while continually analyzing the audio signal to detect when the user stops talking. This analysis may include watching for a lack of speech in the audio signal for a period of time, or an abrupt change in context of the speech (indicating the speech is from another source), or canceling noise or other interfering sound to isolate whether the user is still speaking. Once the device confirms that the user has stopped talking, the device transitions from a transmission mode to a reception mode to await a reply in the conversation.

摘要： Techniques for joining a device of a third user to a communication between a device of a first user and a device of a second user are described herein. For instance, two or more users may utilize respective computing devices to engage in a telephone call, a video call, an instant-messaging session, or any other type of communication in which the users communicate with each other audibly and/or visually. In some instances, a first user of the two users may issue a voice command requesting to join a device of a third user to the communication. One or more computing devices may recognize this voice command and may attempt to join a device of a third user to the communication.

摘要： A speech-based system utilizes a speech interface device located in the home of a user. The system may interact with different users based on different user profiles. The system may include messaging services that generate and/or provide messages to the user through the speech interface device. The speech interface device may have indicators that are capable of being illuminated in different colors. To notify a user regarding the currently active user profile, each user profile is associated with a different color and the color of the active profile is displayed on the speech interface device when the user is interacting with the system. To notify the user regarding awaiting messages, different types of messages are associated with different colors and the colors of the message types of waiting messages are displayed on the speech interface whenever the user is not interacting with the system.

摘要： A user device outputs an unlock code or sends a signal that automatically unlocks a locked container housing a deliverable product when the user device authenticates the container, thereby indicating that the container has been delivered to an intended recipient. The device is associated with a user profile and stores a private key that is inaccessible except by the device. When a product order becomes associated with the user profile, a public key that pairs with the private key is encoded on a storage medium of the container. When the container is brought into proximity with the device, if the device determines that the public key encoded on the storage medium corresponds to the private key stored on the device, the device displays or audibly outputs an unlock code or sends a wireless signal that automatically unlocks the container. The container can also include sensors for detecting theft or tampering.

摘要： A speech-based system is configured to use its audio-based user interface to present various types of device status information such as wireless signal strengths, communication parameters, battery levels, and so forth. In described embodiments, the system is configured to understand spoken user requests for device and system status. For example, the user may speak a request to obtain the current wireless signal strength of the speech-based system. The speech-based system may respond by determining the signal strength and by playing speech or other sound informing the user of the signal strength. Furthermore, the system may monitor operational parameters to detect conditions that may degrade the user experience, and may report such conditions using generated speech or other sounds.
