If I need to pause, I take note of the word I stopped at, hit C-e s, then C-s, type until I reach that line, then press RET.

THanks John. Makes sense!Incremental search usually saves me in such situations! For some reason, I just have not seen it as an issue. But thanks for an interesting take!On Tue, Apr 9, 2024 at 12:48 PM Tim Cross <theophilusx@xxxxxxxxx <mailto:theophilusx@xxxxxxxxx>> wrote:I could be missing something, but as I see it, what voice indexing would provide is for the ability to have a 'voice cursor' (which may or may not be the same as your emacs cursor) tracking of location where the TTS engine is up to when generating speech from the submitted text. The would, for example, enable for the pausing and then subsequent resuming of speech whereby the resumed speech would start from where the speech was previously paused. In some systems, this is very important becasue the system only sends large chunks of speech at a time. For example, I've seen a simple TTS interface for reading files where it will just start reading the file. You odn't have the ability to ask for just a page, paragraph, sentence, line, word. You just ask for it to start speaking and then yuou can pause and resume speech. The other thing you may get is cursor tracking of speech. A cursor might move through the text as it is spoken so that when you pause speech, the cursor is at that point in yhour text. This can be useful for people who want to read along with the speech i.e. the speech is an aid to visual reading. While I can see the potential benefits in having the ability to get and use speech index information, I've not found it very high on my wishlist for emacspeak. This is primarily because emacspeak provides very fined grained control over the size or chunks of speech I send at a time. Depending on what I'm doing, I'll read/browse the data using a movement/chank size which suits my need. For example, I'f I have a large buffer of text I want to read, I'm unlikely to ask emacspeak to just read the whole buffer. Instead, I'm more likely to as it to read by page, paragraph or perhaps sentence. With emacspeak, I find it is very much about moving around using the unit (letter, word, sentence, paragraph, page, buffer) best sutied for what I'm doing. I find this provides an adequate balance between my use case and complexity/consistency across speech servers. This has also enabled me to experiment with different TTS engines. For example, many years ago, I wrote speech servers for the Cepstral TTS engines. These were a commercial TTS engine that at the time, had high quality voices. The additional complexity and overheads involved in a TTS interface model which supported voice indexing would likely hav made this much harder to implement and discouraged the type of experimentation which is at the heart of emacspeak. Likewise, I wonder if we would have had the other TTS engines, some of which have come and gone, like the flite and festival servers or the server written in C, or the existing mac, swiftmac servers or the experimental windows, speech-dispatcher and JS servers that are out there currently in various stages of development. I personally don't see the amount of required effort justifyhing the benefits given we already have the capability to work with varying chunks of speech. Yes, it would provide some convenience, but at a high cost which I feel is hard to justify. However, provided someone can implement something which does not require changes to the existing servers or their design, I would say go for it. A lot can be learnt from implementing a TTS server. In fact, I've learnt a lot from failed attempts to implement TTS servers as there is a considerable amount of subtle and non-obvious aspects to a TTS server which only become clear when you try implementing one, making it a great learning experience. At least it was for me.
