Generating Esperanto Audio

I’m an Esperanto newbie (I just started it this week) and I’m trying to create some private lessons. I tried Lingq’s inbuilt generate audio, and the result was … not great.

I saw Narakeet mentioned somewhere on the forum but it doesn’t have Esperanto, and I’m having trouble finding an alternative. Parol is acceptable quality but you can only do 300 characters at a time. This is absolutely not my area of expertise. Hoping someone knows of something I can use instead?

Lingq is using OpenAI Whisper, which is probably one of the best, but I don’t know how it is the competition right now.

I don’t think Esperanto is amongst their best languages though, it is not listed in the main ones because it could have an error rate above 50%, which is quite understandable considering the usage of the language, and the material available online for free.

Have you tried to ask in some specialised forum dedicated to this language?

No, I haven’t–I’ll look into that

It’s not the accuracy that seems to be the issue–as far as I can tell the generated audio is accurate–but the voice is strangely distorted/echoey (hard to describe). It’s easier to understand slowed down, but still, I’d find it really difficult to listen to that for more than a few minutes at a time.

I made a mistake, Whisper is for generating the transcript from the audio recognition, if I’m not wrong.

I don’t know if TTS sentence by sentence, and the entire transcript, is the same technology though.

In any case, as far as I know, the voice depends on the device/system you are using. If you are on the web-app or iOS, you can have different options. I don’t remember where right now, but you can change the voice somewhere in the settings, so you check if there are different options/voices, and change them. In this case you need to regenerate a new audio to check with the new voice.

I definitely understand you with the “robotic” voice, but things could improve along the time. I think there are constant updates and improvements on this matter. However, check if there are other voices available.

One service that I had read being good is Speechify, but I’ve never tried it. They have Esperanto as well, and they should have “natural” voices. You should be able to try it for free.

Unfortunately, LingQ Esperanto only has one voice option listed. I was waiting to reply until I heard back from Speechify, as they have multiple products advertised on their site and not all of them list all the languages. I’ve got a reply to my enquiry now, and it seems in order to create Esperanto audio files I’d need to subscribe to their full-on multi-product service which is professionally priced. Haha no.

I have given up on generating my own audio files for Esperanto (Narakeet has every other language I’m interested in and sounds pretty good). Thankfully I’ve found an old CI course on Youtube, La Pasporto al la Tuta Mondo, which is fantastic for beginners (as long as you find the over-acting amusing rather than annoying, which I do). I haven’t looked into importing it into LingQ yet–not sure if it has accurate Esperanto subtitles, if not maybe I could find a transcript somewhere–but for now I’m finding just watching/listening to them on repeat very effective. I’ve also got hold of some beginner-level books, and considering how regular Esperanto is, I’m less concerned about mis-learning pronunciation by reading without accompanying audio.

Yeah, Esperanto and Latin are quite frustrating if you try to make the text-to-speech work :face_with_spiral_eyes:
