Problems solved by technology

Moreover, networks often operate under different and changing impairments, conditions, outages, etc., thereby inadvertently altering the transmitted audio signal
In these types of environments, audio signals that would otherwise be recognized under normal conditions may become completely unintelligible

Embodiment Construction

[0022] Turning to FIG. 1 , a block diagram of a speech processing system is shown in accordance with some embodiments. As shown, voice detector 100 may be connected to network 140 and configured to connect to one or more of test unit(s) 110 , IVR server 120 , or notification endpoint(s) 130 . In some embodiments, voice detector 100 may be configured to monitor communications between test unit(s) 110 and IVR server 120 or notification endpoint(s) 130 . In other embodiments, voice detector 100 may be configured to initiate communication with IVR server 120 or notification endpoint(s) 130 . In yet another embodiment, the voice detector 100 may be configured to receive one or more commands from the testing unit(s) 110 . For example, in response to receiving one or more commands, voice detector 100 may initiate, terminate, alter, or otherwise control the network testing process, and the like. The protocol used to effectuate the communications occurring in FIG. 1 may be selected, ...

Abstract

Systems and methods for speech processing in telecommunication networks are described. In some embodiments, a method may include receiving speech transmitted over a network, causing the speech to be converted to text, and identifying the speech as predetermined speech in response to the text matching a stored text associated with the predetermined speech. The stored text may have been obtained, for example, by subjecting the predetermined speech to a network impairment condition. The method may further include identifying terms within the text that match terms within the stored text (e.g., despite not being identical to each other), calculating a score between the text and the stored text, and determining that the text matches the stored text in response to the score meeting a threshold value. In some cases, the method may also identify one of a plurality of speeches based on a selected one of a plurality of stored texts.

Description

technical field [0001] This specification relates generally to speech processing, and more particularly to systems and methods for processing speech in telecommunications networks. Background technique [0002] There are various situations in which verbal sentences or prompts may be transmitted between two endpoints of a telecommunications network. Examples of telecommunications equipment configured to transmit audio or voice signals include, but are not limited to, Interactive Voice Response (IVR) servers and automated announcement systems. Additionally, there are instances where a telecommunications company, carrier, or other entity may wish to verify and / or identify audio played by such devices. [0003] For demonstration reasons, a bank may wish to test whether an appropriate greeting message is provided to an inbound caller depending on the time of the call. In this case, the bank may need to verify, for example, that the first automated message is played when a phone...
