Human-machine interaction

An electronic device, comprising:

• at least one processor;
• and
• a memory communicatively connected to the at least one processor, wherein the memory stores instructions configured to be executed by the at least one processor, the instructions, when executed by the at least one processor, causing the at least one processor to perform acts, comprising:
• generating reply text of a reply to a received speech signal based on the speech signal;
• generating a reply speech signal corresponding to the reply text based on a mapping relationship between a speech signal unit and a text unit, the reply text including a group of text units, and the generated reply speech signal including a group of speech signal units corresponding to the group of text units;
• determining an identifier of at least one of an expression and action based on the reply text, wherein the at least one of the expression and action is presented by a virtual object;
• and
• generating an output video including the virtual object based on the reply speech signal and the identifier of the at least one of the expression and action, the output video including a lip shape sequence determined based on the reply speech signal and to be presented by the virtual object.

A non-transitory computer-readable storage medium storing computer instructions that, when executed by at least one processor of a computer, cause the computer to perform acts, comprising:

• generating reply text of a reply to a received speech signal based on the speech signal;
• generating a reply speech signal corresponding to the reply text based on a mapping relationship between a speech signal unit and a text unit, the reply text including a group of text units, and the generated reply speech signal including a group of speech signal units corresponding to the group of text units;
• determining an identifier of at least one of an expression and action based on the reply text, wherein the at least one of the expression and action is presented by a virtual object;
• and
• generating an output video including the virtual object based on the reply speech signal and the identifier of the at least one of the expression and action, the output video including a lip shape sequence determined based on the reply speech signal and to be presented by the virtual object.
