[0021] In this invention, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c alone can represent: a alone, b alone, c alone, a combination of a and b, a combination of a and c, a combination of b and c, or a, b, and c, where a, b, and c can be single or multiple. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] The terms “center,” “longitudinal,” “lateral,” “up,” “down,” “left,” “right,” “front,” and “back,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] The terms "connected" and "connected" should be interpreted broadly. For example, in circuit structures, "connected" or "connected" can refer not only to physical connections but also to electrical or signal connections. This could be a direct connection (physical connection) or an indirect connection via at least one intermediate component, as long as the circuit is connected. It could also refer to the internal connection between two components. Similarly, a signal connection can refer to a connection via a circuit or a media, such as radio waves. Those skilled in the art will understand the specific meaning of these terms in this invention based on the specific circumstances.

[0024] Existing translation devices mostly exist as standalone headphones or dedicated hardware, making them incompatible with traditional audio systems (such as mixing consoles, amplifiers, and analog microphones). This necessitates additional modifications or dedicated interfaces, raising the barrier to entry and increasing hardware modification costs. Furthermore, existing translation products lack real-time monitoring capabilities, preventing users from verifying audio quality during translation. They also fall short in multilingual switching and noise reduction accuracy, failing to meet the demands for real-time, low-latency, and high-quality translation in various scenarios. Therefore, there is an urgent need for a device that can directly connect to traditional audio systems via a standard analog interface, while also providing local noise reduction, wireless networking, multilingual translation, and real-time monitoring capabilities, thus enabling the intelligentization of traditional audio equipment.

[0025] To overcome the shortcomings of the aforementioned related technologies, this utility model provides an intelligent translation device with multiple external interfaces. This intelligent translation device includes an analog audio input interface and an analog audio output interface. These interfaces enable voice input and translated voice output. Users can connect different voice input and playback devices to the analog audio input and output interfaces to suit various work scenarios. Furthermore, the intelligent translation device also features a wireless communication module. This module enables the transmission of audio signals to a cloud-based translation server for online translation and the reception of translated voice signals, thus improving translation efficiency.

[0031] In one embodiment of this utility model, the cloud translation server 19 is equipped with a TTS (Text To Speech) algorithm module and a speech synthesis module. The cloud translation server 19 can translate the speech signal to be translated into the target speech signal, and send the translated second digital audio signal to the digital-to-analog conversion module 18.
