Change Text-To-Speech By Using Automator

Mac OS X has a nice feature: Text-To-Speech. You can select a text and let Mac OS to read the text. Since OS X 10.8, Apple added Chinese speech support. For me, English and Chinese are two voices I used most of time. This can be set in System Preferences->Dictation & Speech, where a default voice can be set.

One thing bothers me is that it is so inconvenient to switch between voices. What I would like is a convenient way, such as short-cut-keys, to make change of voices. For me, I would like to switch between Alex to read English and Ting-Ting for Chinese quickly.

Finally, I found a way to do it. It is actually very easy to do it. This can be done by using Automator. Here are steps.

First, launch Automator from Spotlight (pressing command+space, and type Automator). Select Service  type documentation.

Create Services

Within workflow, only two items are needed: Service receives selected text, and Speak Text:

Save the service as "SpeechByAlex".

Repeat the same step to create another service with Ting-Ting as voice, and save it as "SpeechByTingTing".

Note: the services are saved in the local user's Library->Services folder.

Define Shortcut Keys

The next step is to define shortcut keys for those two services.

Open System Preferences->Keyboard. Select Keyboard Shortcuts tab. On the left panel, select Services. Find two services under Text group.

I used Control+Shift+Command+A for Alex, and Control+Shift+Command+T for Ting-Ting.

iMac 27 Power Supply Failure

I found my iMac 27 dead after I came back from my 3 week trip to China. I turned power off before I left. When I tried to turn on my iMac 27 as I came back, the screen stays black, nothing happening. I made an appointment with Apple Help Desk. I had to leave my Mac there since a support staff could not tell what's wrong at that time. He told me two possibilities: one is power supply and another is logic board.

Fortunately, after three days I got email from Apple store my Mad ready for pick up. It was power supply issue. I told them if it is the logic board issue, contact me first. To repair or replay logic board, it would cost me about $500 or more. I was lucky. The part of PS is $69.00, and the labour is $39.00. I was told that the labour cost was reduced recently. It was $100+ before.

I am planning to update my iMac 27 so that I will get at least one year warranty. This time, I think, I'll get extended warranty with three year coverage and phone support.
