Systems and methods for audio enhancement and conversion

A method by a computing device, the method comprising:

• accessing a first digital audio file stored in one or more memory units, the first digital audio file comprising a plurality of spoken instructions;
• converting the first digital audio file to a first spectrogram image;
• applying a filter to determine whether an image quality of the first spectrogram image is below a predetermined image quality;
• in response to determining that the image quality of the first spectrogram image is below the predetermined image quality, generating a second spectrogram image from the first spectrogram image using a training model, the second spectrogram image having a higher image quality than the image quality of the first spectrogram image;
• converting the second spectrogram image to a second digital audio file;
• converting, using an encoder, the second digital audio file into a plurality of vectors, each vector corresponding to a particular one of the plurality of spoken instructions;
• identifying a plurality of related vectors that each correspond to a particular one of the plurality of spoken instructions from the plurality of vectors;
• concatenating the plurality of related vectors that each correspond to a particular one of the plurality of spoken instructions together in order to create a plurality of concatenated vectors;
• generating, using a decoder on the plurality of concatenated vectors, a third digital audio file, the third digital audio file comprising concatenated spoken instructions from the first digital audio file;
• and
• storing the third digital audio file in the one or more memory units.

One or more computer-readable non-transitory storage media embodying software that is operable when executed by a hardware processor to:

• access a first digital audio file stored in one or more memory units, the first digital audio file comprising a plurality of spoken instructions;
• convert the first digital audio file to a first spectrogram image;
• apply a filter to determine whether an image quality of the first spectrogram image is below a predetermined image quality;
• in response to determining that the image quality of the first spectrogram image is below the predetermined image quality, generate a second spectrogram image from the first spectrogram image using a training model, the second spectrogram image having a higher image quality than the image quality of the first spectrogram image;
• convert the second spectrogram image to a second digital audio file;
• convert, using an encoder, the second digital audio file into a plurality of vectors, each vector corresponding to a particular one of the plurality of spoken instructions;
• identify a plurality of related vectors that each correspond to a particular one of the plurality of spoken instructions from the plurality of vectors;
• concatenate the plurality of related vectors that each correspond to a particular one of the plurality of spoken instructions together in order to create a plurality of concatenated vectors;
• generate, using a decoder on the plurality of concatenated vectors, a third digital audio file, the third digital audio file comprising concatenated spoken instructions from the first digital audio file;
• and
• store the third digital audio file in the one or more memory units.
