2. Speech recognition - Wikipedia

   en.wikipedia.org/wiki/Speech_recognition

   Speech recognition is an interdisciplinary subfield of computer science and computational linguistics that develops methodologies and technologies that enable the recognition and translation of spoken language into text by computers. It is also known as automatic speech recognition ( ASR ), computer speech recognition or speech-to-text ( STT ).

3. Audio file format - Wikipedia

   en.wikipedia.org/wiki/Audio_file_format

   An audio file format is a file format for storing digital audio data on a computer system. The bit layout of the audio data (excluding metadata) is called the audio coding format and can be uncompressed, or compressed to reduce the file size, often using lossy compression. The data can be a raw bitstream in an audio coding format, but it is ...

4. Speech synthesis - Wikipedia

   en.wikipedia.org/wiki/Speech_synthesis

   See media help. Speech synthesis is the artificial production of human speech. A computer system used for this purpose is called a speech synthesizer, and can be implemented in software or hardware products. A text-to-speech ( TTS) system converts normal language text into speech; other systems render symbolic linguistic representations like ...

5. Comparison of audio coding formats - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_audio_coding...

   For example, MP3 and AAC dominate the personal audio market in terms of market share, though many other formats are comparably well suited to fill this role from a purely technical standpoint. First public release date is first of either specification publishing or source releasing, or in the case of closed-specification, closed-source codecs ...

6. Adaptive Multi-Rate audio codec - Wikipedia

   en.wikipedia.org/wiki/Adaptive_Multi-Rate_audio...

   The Adaptive Multi-Rate (AMR, AMR-NB or GSM-AMR) audio codec is an audio compression format optimized for speech coding.AMR is a multi-rate narrowband speech codec that encodes narrowband (200–3400 Hz) signals at variable bit rates ranging from 4.75 to 12.2 kbit/s with toll quality [3] speech starting at 7.4 kbit/s.

7. Audio converter - Wikipedia

   en.wikipedia.org/wiki/Audio_converter

   An audio converter is a software or hardware tool that converts audio files from one format to another. This process is often necessary when users encounter compatibility issues with different devices, applications, or platforms that support specific audio file formats. Audio converters can be employed for a variety of purposes, ranging from ...
