Question: What is the most typical use for a convolutional neural network?

Option 1: 'speech recognition' — This is a plausible application because CNNs can process spectrograms or other time-frequency representations, but it is not the most typical or canonical use. In practice, many sequence models or RNNs/LSTMs are favored for raw speech tasks, and CNNs used for speech are more specialized rather than the standard example.

Option 2: 'image recognition' — This is widely recognized as the classic, textbook use of convolutional neural networks. Convolutions excel at capturing spatial hierarchies, textures, edges, and shapes in images, and many standard architectures (like LeNet, AlexNet, VGG, ResNet) were developed specifically for image-related tasks. This aligns with the common understanding of CNNs’ strengths.

Option 3: 'all of these are typical' — While CNNs can be applied to multiple domains, saying all are typical overstates the case. Speech recognition and word recognition can employ CNNs, but they are not the most representative or universal use compared to image recognition. The wording makes this option misleading.

Option 4: 'word recognition' — Similar to speech recognition, CNNs can be used in some word or character recognition scenarios, especially when treating inputs as images (e.g., handwriting recognition). However, this is not the standard or most typical application when people first learn about CNNs.

Summary: Each option describes a plausible use in certain contexts, but image recognition best captures the quintessential, canonical strength and historical origin of convolutional neural networks. The other options describe secondary or more specialized uses rather than the most typical one.
