Example 1

Based on the above mobile terminal, an embodiment of the present invention provides a bidirectional translation method, and fig. 3 is a first flowchart of the bidirectional translation method according to the embodiment of the present invention, as shown in fig. 3, the method includes the following steps:

step S301, acquiring voices input by a user through a main Mic and an auxiliary Mic, and generating a first path of PCM audio stream and a second path of PCM audio stream of the voices input by the user, wherein the first path of PCM audio stream corresponds to the voices acquired by the main Mic, the second path of PCM audio stream corresponds to the voices acquired by the auxiliary Mic, the main Mic is arranged at the bottom of a mobile terminal, and the auxiliary Mic is arranged at the top of the mobile terminal;

step S302, comparing the gain of the first path of PCM audio stream with the gain of the second path of PCM audio stream, and determining a language translation strategy of the user, wherein the language translation strategy comprises the steps of translating local voice into foreign language and translating the foreign language into the local voice;

step S303, translating the recognized user input voice according to the language translation strategy of the user;

and step S304, outputting the translation result of the voice input by the user.

Through the steps, the voice recorded by the user is collected through a main Mic and an auxiliary Mic, and a first path of PCM audio stream and a second path of PCM audio stream of the voice recorded by the user are generated, wherein the first path of PCM audio stream corresponds to the voice collected by the main Mic, and the second path of PCM audio stream corresponds to the voice collected by the auxiliary Mic; performing gain comparison on the first path of PCM audio stream and the second path of PCM audio stream, and determining a language translation strategy of the user, wherein the language translation strategy comprises translation of local voice into a foreign language, and translation of the foreign language into local voice; translating the recognized user input voice according to the language translation strategy of the user; the translation result of the voice input by the user is output, the problem of low efficiency caused by the fact that the strategy of continuously and manually changing the translation language is needed in bidirectional translation in the related technology is solved, the translation strategy does not need to be manually changed, the translation efficiency is improved, and the user experience is improved.

In an optional embodiment, before the primary Mic and the secondary Mic collect voices recorded by a user and generate a first path of PCM audio stream and a second path of PCM audio stream of the voices recorded by the user, the user sets local voices and receives a setting instruction for setting local languages; and setting a local language according to the setting instruction. The translated foreign language is then selected.

In another alternative embodiment, the mobile terminal may also automatically generate the local language, and the user of the mobile terminal opens the international roaming function for the SIM card used by the user, so that the user can access PLMNs in other countries. For example, a chinese user goes from china to the united states and opens an international roaming function for a mobile terminal using an SIM card, and after the user arrives in the united states, the mobile terminal is powered on and starts up and automatically sets a translation language, and obtains a public land mobile network PLMN code related to the mobile terminal; determining a language category of a country associated with a user of the mobile terminal based on the PLMN code; and automatically setting the target language type and the source language type of the translation tool according to the language type of the country related to the user of the mobile terminal, automatically setting the source language and the target language of the translation tool, facilitating the operation of the user and saving the communication cost. The method for setting the translation language specifically comprises the following steps:

and acquiring the RPLMN code from the memory of the mobile terminal. Before the mobile terminal is powered off or disconnected last time, the mobile terminal accesses the China mobile communication network, and the mobile terminal takes the PLMN code of the China mobile communication network as the RPLMN and stores the RPLMN in the memory. For example, if the mobile communication network provided by the operator "china mobile" is accessed before the mobile terminal is powered off or disconnected last time, the corresponding PLMN code 46000 is stored in the memory as the RPLMN code. When the user arrives in the united states and starts the mobile terminal, the mobile terminal obtains the RPLMN code 46000 from the memory.

And judging whether the mobile terminal can access the mobile communication network identified by the RPLMN code. When the mobile terminal can access the mobile communication network identified by the RPLMN code, the setting of the translation language is terminated. When the mobile terminal can access the mobile communication network identified by the RPLMN code, the user is not required to set the translation language type of the translation tool at the moment, which indicates that the user does not go to other countries. And when the mobile terminal can not access the mobile communication network identified by the RPLMN code, acquiring the HPLMN code of the home public land mobile network of the SIM card of the mobile terminal. When the mobile terminal can not access the mobile communication network identified by the RPLMN code, the mobile terminal acquires the HPLMN code of the SIM card to further judge whether the user goes to other countries, which indicates that the user may go to other countries.
